How to configure a label for Rights Management protection

You can protect your most sensitive documents and emails by using a Rights Management service. This service uses encryption, identity, and authorization policies to help prevent data loss. The protection is applied with a label that is configured to use Rights Management protection for documents and emails, and users can also select the Do not forward button in Outlook.

When your label is configured with the protection setting of Azure (cloud key), under the covers, this action creates and configures a protection template that can then be accessed by services and applications that integrate with Rights Management templates. For example, Exchange Online and mail flow rules, and Outlook on the web.

How the protection works

When a document or email is protected by a Rights Management service, it is encrypted at rest and in transit. It can then be decrypted only by authorized users. This encryption stays with the document or email, even if it is renamed. In addition, you can configure usage rights and restrictions, such as the following examples:

  • Only users within your organization can open the company-confidential document or email.

  • Only users in the marketing department can edit and print the promotion announcement document or email, while all other users in your organization can only read this document or email.

  • Users cannot forward an email or copy information from it that contains news about an internal reorganization.

  • The current price list that is sent to business partners cannot be opened after a specified date.

For more information about the Azure Rights Management protection and how it works, see What is Azure Rights Management?

Important

To configure a label to apply this protection, the Azure Rights Management service must be activated for your organization. For more information, see Activating the protection service from Azure Information Protection.

When the label applies protection, a protected document is not suitable to be saved on SharePoint or OneDrive. These locations do not support the following features for protected files: Co-authoring, Office for the web, search, document preview, thumbnail, eDiscovery, and data loss prevention (DLP).

Tip

When you migrate your labels to unified sensitivity labels and publish them from the Microsoft 365 compliance center, labels that apply protection are then supported for these locations. For more information, see Enable sensitivity labels for Office files in SharePoint and OneDrive.

Exchange does not have to be configured for Azure Information Protection before users can apply labels in Outlook to protect their emails. However, until Exchange is configured for Azure Information Protection, you do not get the full functionality of using Azure Rights Management protection with Exchange. For example, users cannot view protected emails on mobile phones or with Outlook on the web, protected emails cannot be indexed for search, and you cannot configure Exchange Online DLP for Rights Management protection. To ensure that Exchange can support these additional scenarios, see the following resources:

To configure a label for protection settings

  1. If you haven't already done so, open a new browser window and sign in to the Azure portal. Then navigate to the Azure Information Protection pane.

    For example, in the search box for resources, services, and docs: Start typing Information and select Azure Information Protection.

  2. From the Classifications > Labels menu option: On the Azure Information Protection - Labels pane, select the label you want to change.

  3. On the Label pane, locate Set permissions for documents and emails containing this label, and select one of the following options:

    • Not configured: Select this option if the label is currently configured to apply protection and you no longer want the selected label to apply protection. Then go to step 11.

      The previously configured protection settings are retained as an archived protection template, and will be displayed again if you change the option back to Protect. You do not see this template in the Azure portal but if necessary, you can still manage the template by using PowerShell. This behavior means that content remains accessible if it has this label with the previously applied protection settings.

      When a label with this Not configured protection setting is applied:

      • If the content was previously protected without using a label, that protection is preserved.

      • If the content was previously protected with a label, that protection is removed if the user applying the label has permissions to remove Rights Management protection. This requirement means that the user must have the Export or Full Control usage right. Or, be the Rights Management owner (which automatically grants the Full Control usage right), or a super user for Azure Rights Management.

        If the user doesn't have permissions to remove protection, the label cannot be applied and the following message is displayed: Azure Information Protection cannot apply this label. If this problem persists, contact your administrator.

    • Protect: Select this option to apply protection, and then go to step 4.

    • Remove Protection: Select this option to remove protection if a document or email is protected. Then go to step 11.

      If the protection was applied with a label or protection template, the protection settings are retained as an archived protection template, and will be displayed again if you change the option back to Protect. You do not see this template in the Azure portal but if necessary, you can still manage the template by using PowerShell. This behavior means that content remains accessible if it has this label with the previously applied protection settings.

      Note that for a user to successfully apply a label that has this option, that user must have permissions to remove Rights Management protection. This requirement means that the user must have the Export or Full Control usage right. Or, be the Rights Management owner (which automatically grants the Full Control usage right), or a super user for Azure Rights Management.

      If the user applying the label with this setting does not have permissions to remove Rights Management protection, the label cannot be applied and the following message is displayed: Azure Information Protection cannot apply this label. If this problem persists, contact your administrator.

  4. If you selected Protect, the Protection pane automatically opens if one of the other options were previously selected. If this new pane does not automatically open, select Protection:

    Configure protection for an Azure Information Protection label

  5. On the Protection pane, select Azure (cloud key) or HYOK (AD RMS).

    In most cases, select Azure (cloud key) for your permission settings. Do not select HYOK (AD RMS) unless you have read and understood the prerequisites and restrictions that accompany this "hold your own key" (HYOK) configuration. For more information, see Hold your own key (HYOK) requirements and restrictions for AD RMS protection. To continue the configuration for HYOK (AD RMS), go to step 9.

  6. Select one of the following options:

    • Set permissions: To define new protection settings in this portal.

    • Set user-defined permissions (Preview): To let users specify who should be granted permissions and what those permissions are. You can then refine this option and choose Outlook only, or Word, Excel, PowerPoint, and File Explorer. This option is not supported, and does not work, when a label is configured for automatic classification.

      If you choose the option for Outlook: The label is displayed in Outlook and the resulting behavior when users apply the label is the same as the Do Not Forward option.

      If you choose the option for Word, Excel, PowerPoint, and File Explorer: When this option is set, the label is displayed in these applications. The resulting behavior when users apply the label is to display the dialog box for users to select custom permissions. In this dialog box, users choose one of the predefined permissions levels, browse to or specify the users or groups, and optionally, set an expiry date. Make sure that users have instructions and guidance how to supply these values.

      Note

      Azure Information Protection support for setting user-defined permissions is currently in PREVIEW. The Azure Preview Supplemental Terms include additional legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.

    • Select a predefined template: To use one of the default templates or a custom template that you've configured. Note that this option does not display for new labels, or if you are editing a label that previously used the Set permissions option.

      To select a predefined template, the template must be published (not archived) and must not be linked already to another label. When you select this option, you can use an Edit Template button to convert the template into a label.

      If you are used to creating and editing custom templates, you might find it useful to reference Tasks that you used to do with the Azure classic portal.

  7. If you selected Set permissions for Azure (cloud key), this option lets you select users and usage rights.

    If you don't select any users and select OK on this pane, followed by Save on the Label pane: The label is configured to apply protection such that only the person who applies the label can open the document or email with no restrictions. This configuration is sometimes referred to as "Just for me" and might be the required outcome, so that a user can save a file to any location and be assured that only they can open it. If this outcome matches your requirement and others are not required to collaborate on the protected content, do not select Add permissions. After saving the label, the next time you open this Protection pane, you see IPC_USER_ID_OWNER displayed for Users, and Co-Owner displayed for Permissions to reflect this configuration.

    To specify the users you want to be able to open protected documents and emails, select Add permissions. Then on the Add permissions pane, select the first set of users and groups who will have rights to use the content that will be protected by the selected label:

    • Choose Select from the list where you can then add all users from your organization by selecting Add <organization name> - All members. This setting excludes guest accounts. Or, you can select Add any authenticated users, or browse the directory.

      When you choose all members or browse the directory, the users or groups must have an email address. In a production environment, users and groups nearly always have an email address, but in a simple testing environment, you might need to add email addresses to user accounts or groups.

      More information about Add any authenticated users

      This setting doesn't restrict who can access the content that the label protects, while still encrypting the content and providing you with options to restrict how the content can be used (permissions), and accessed (expiry and offline access). However, the application opening the protected content must be able to support the authentication being used. For this reason, federated social providers such as Google, and onetime passcode authentication should be used for email only, and only when you use Exchange Online and the new capabilities from Office 365 Message Encryption. Microsoft accounts can be used with the Azure Information Protection viewer and Office 365 apps (Click-to-Run).

      Some typical scenarios for the any authenticated users setting:

      • You don't mind who views the content, but you want to restrict how it is used. For example, you do not want the content to be edited, copied, or printed.
      • You don't need to restrict who accesses the content, but you want to be able to track who opens it and potentially, revoke it.
      • You have a requirement that the content must be encrypted at rest and in transit, but it doesn't require access controls.
    • Choose Enter details to manually specify email addresses for individual users or groups (internal or external). Or, use this option to specify all users in another organization by entering any domain name from that organization. You can also use this option for social providers, by entering their domain name such as gmail.com, hotmail.com, or outlook.com.

      Note

      If an email address changes after you select the user or group, see the Considerations if email addresses change section from the planning documentation.

      As a best practice, use groups rather than users. This strategy keeps your configuration simpler and makes it less likely that you have to update your label configuration later and then reprotect content. However, if you make changes to the group, keep in mind that for performance reasons, Azure Rights Management caches the group membership.

    When you have specified the first set of users and groups, select the permissions to grant these users and groups. For more information about the permissions that you can select, see Configuring usage rights for Azure Information Protection. However, applications that support this protection might vary in how they implement these permissions. Consult their documentation and do your own testing with the applications that users use to check the behavior before you deploy the template for users.

    If required, you can now add a second set of users and groups with usage rights. Repeat until you have specified all the users and groups with their respective permissions.

    Tip

    Consider adding the Save As, Export (EXPORT) custom permission and grant this permission to data recovery administrators or personnel in other roles that have responsibilities for information recovery. If needed, these users can then remove protection from files and emails that will be protected by using this label or template. This ability to remove protection at the permission level for a document or email provides more fine-grained control than the super user feature.

    For all the users and groups that you specified, on the Protection pane, now check whether you want to make any changes to the following settings. Note that these settings, as with the permissions, do not apply to the Rights Management issuer or Rights Management owner, or any super user that you have assigned.

    Information about the protection settings
    Setting More information Recommended setting
    File Content Expiration Define a date or number of days for when documents that are protected by these settings should not open for the selected users. For emails, expiration isn't always enforced because of caching mechanisms used by some email clients.

    You can specify a date or specify a number of days starting from the time that the protection is applied to the content.

    When you specify a date, it is effective midnight, in your current time zone.
    Content never expires unless the content has a specific time-bound requirement.
    Allow offline access Use this setting to balance any security requirements that you have (includes access after revocation) with the ability for the selected users to open protected content when they don't have an internet connection.

    If you specify that content is not available without an internet connection or that content is only available for a specified number of days, when that threshold is reached, these users must be reauthenticated and their access is logged. When this happens, if their credentials are not cached, the users are prompted to sign in before they can open the document or email.

    In addition to reauthentication, the policy and the user group membership is reevaluated. This means that users could experience different access results for the same document or email if there are changes in the policy or group membership from when they last accessed the content. That could include no access if the document has been revoked.
    Depending on how sensitive the content is:

    - Number of days the content is available without an internet connection = 7 for sensitive business data that could cause damage to the business if shared with unauthorized people. This recommendation offers a balanced compromise between flexibility and security. Examples include contracts, security reports, forecast summaries, and sales account data.

    - Never for very sensitive business data that would cause damage to the business if it was shared with unauthorized people. This recommendation prioritizes security over flexibility, and ensures that if the document is revoked, all authorized users immediately cannot open the document. Examples include employee and customer information, passwords, source code, and pre-announced financial reports.

    When you have finished configuring the permissions and settings, click OK.

    This grouping of settings creates a custom template for the Azure Rights Management service. These templates can be used with applications and services that integrate with Azure Rights Management. For information about how computers and services download and refresh these templates, see Refreshing templates for users and services.

  8. If you selected Select a predefined template for Azure (cloud key), click the drop-down box and select the template that you want to use to protect documents and emails with this label. You do not see archived templates or templates that are already selected for another label.

    If you select a departmental template, or if you have configured onboarding controls:

    • Users who are outside the configured scope of the template or who are excluded from applying Azure Rights Management protection still see the label but cannot apply it. If they select the label, they see the following message: Azure Information Protection cannot apply this label. If this problem persists, contact your administrator.

      Note that all published templates are always shown, even if you are configuring a scoped policy. For example, you are configuring a scoped policy for the Marketing group. The templates that you can select are not restricted to templates that are scoped to the Marketing group and it's possible to select a departmental template that your selected users cannot use. For ease of configuration and to minimize troubleshooting, consider naming the departmental template to match the label in your scoped policy.

  9. If you selected HYOK (AD RMS), select either Set AD RMS templates details or Set user defined permissions (Preview). Then specify the licensing URL of your AD RMS cluster.

    For instructions to specify a template GUID and your licensing URL, see Locating the information to specify AD RMS protection with an Azure Information Protection label.

    The user-defined permissions option lets users specify who should be granted permissions and what those permissions are. You can then refine this option and choose Outlook only (the default), or Word, Excel, PowerPoint, and File Explorer. This option is not supported, and does not work, when a label is configured for automatic classification.

    If you choose the option for Outlook: The label is displayed in Outlook and the resulting behavior when users apply the label is the same as the Do Not Forward option.

    If you choose the option for Word, Excel, PowerPoint, and File Explorer: When this option is set, the label is displayed in these applications. The resulting behavior when users apply the label is to display the dialog box for users to select custom permissions. In this dialog box, users choose one of the predefined permissions levels, browse to or specify the users or groups, and optionally, set an expiry date. Make sure that users have instructions and guidance how to supply these values.

  10. Click OK to close the Protection pane and see your choice of User defined or your chosen template display for the Protection option in the Label pane.

  11. On the Label pane, click Save.

  12. On the Azure Information Protection pane, use the PROTECTION column to confirm that your label now displays the protection setting that you want:

    • A check mark if you have configured protection.

    • An x mark to denote cancellation if you have configured a label to remove protection.

    • A blank field when protection is not set.

When you clicked Save, your changes are automatically available to users and services. There's no longer a separate publish option.

Example configurations

The All Employees and Recipients Only sublabels from the Confidential and High Confidential labels from the default policy provide examples of how you can configure labels that apply protection. You can also use the following examples to help you configure protection for different scenarios.

For each example that follows, on your <label name> pane, select Protect. If the Protection pane doesn't automatically open, select Protection to open this pane that lets you select your protection configuration options:

Configuing an Azure Information Protection label for protection

Example 1: Label that applies Do Not Forward to send a protected email to a Gmail account

This label is available only in Outlook and is suitable when Exchange Online is configured for the new capabilities in Office 365 Message Encryption. Instruct users to select this label when they need to send a protected email to people using a Gmail account (or any other email account outside your organization).

Your users type the Gmail email address in the To box. Then, they select the label and the Do Not Forward option is automatically added to the email. The result is that recipients cannot forward the email, or print it, copy from it, or save the email outside their mailbox by using the Save As option.

  1. On the Protection pane, make sure that Azure (cloud key) is selected.

  2. Select Set user-defined permissions (Preview).

  3. Make sure that the following option is selected: In Outlook apply Do Not Forward.

  4. If selected, clear the following option: In Word, Excel, PowerPoint and File Explorer prompt user for custom permissions.

  5. Click OK on the Protection pane, and then click Save on the Label pane.

Example 2: Label that restricts read-only permission to all users in another organization, and that supports immediate revocation

This label is suitable for sharing (read-only) very sensitive documents that always require an internet connection to view it. If revoked, users will not be able to view the document the next time they try to open it.

This label is not suitable for emails.

  1. On the Protection pane, make sure that Azure (cloud key) is selected.

  2. Make sure that the Set permissions option is selected, and then select Add permissions.

  3. On the Add permissions pane, select Enter details.

  4. Enter the name of a domain from the other organization, for example, fabrikam.com. Then select Add.

  5. From Choose permissions from preset, select Viewer, and then select OK.

  6. Back on the Protection pane, for Allow offline access setting, select Never.

  7. Click OK on the Protection pane, and then click Save on the Label pane.

Example 3: Add external users to an existing label that protects content

The new users that you add will be able open documents and emails that have already been protected with this label. The permissions that you grant these users can be different from the permissions that the existing users have.

  1. On the Protection pane, make sure Azure (cloud key) is selected.

  2. Ensure that Set permissions is selected, and then select Add permissions.

  3. On the Add permissions pane, select Enter details.

  4. Enter the email address of the first user (or group) to add, and then select Add.

  5. Select the permissions for this user (or group).

  6. Repeat steps 4 and 5 for each user (or group) that you want to add to this label. Then click OK.

  7. Click OK on the Protection pane, and then click Save on the Label pane.

Example 4: Label for protected email that supports less restrictive permissions than Do Not Forward

This label cannot be restricted to Outlook but does provide less restrictive controls than using Do Not Forward. For example, you want the recipients to be able to copy from the email or an attachment, or save and edit an attachment.

If you specify external users who do not have an account in Azure AD:

  • The label is suitable for email when Exchange Online is using the new capabilities in Office 365 Message Encryption.

  • For Office attachments that are automatically protected, these documents are available to view in a browser. To edit these documents, download and edit them with Office 365 apps (Click-to-Run), and a Microsoft account that uses the same email address. More information

Note

Exchange Online is rolling out a new option, encrypt-only. This option is not available for label configuration. However, when you know who the recipients will be, you can use this example to configure a label with the same set of usage rights.

When your users specify the email addresses in the To box, the addresses must be for the same users that you specify for this label configuration. Because users can belong to groups and have more than one email address, the email address that they specify does not have to match the email address that you specify for the permissions. However, specifying the same email address is the easiest way to ensure that the recipient will be successfully authorized. For more information about how users are authorized for permissions, see Preparing users and groups for Azure Information Protection.

  1. On the Protection pane, make sure that Azure (cloud key) is selected.

  2. Make sure Set permissions is selected, and select Add permissions.

  3. On the Add permissions pane: To grant permissions to users in your organization, select Add <organization name> - All members to select all users in your tenant. This setting excludes guest accounts. Or, select Browse directory to select a specific group. To grant permissions to external users or if you prefer to type the email address, select Enter details and type the email address of the user, or Azure AD group, or a domain name.

    Repeat this step to specify additional users who should have the same permissions.

  4. For Choose permissions from preset, select Co-Owner, Co-Author, Reviewer, or Custom to select the permissions that you want to grant.

    Note: Do not select Viewer for emails and if you do select Custom, make sure that you include Edit and Save.

    To select the same permissions that match the Encrypt option from Exchange Online, which applies encryption without additional restrictions, select Custom. Then select all permissions except Save As, Export (EXPORT) and Full Control (OWNER).

  5. To specify additional users who should have different permissions, repeat steps 3 and 4.

  6. Click OK on the Add permissions pane.

  7. Click OK on the Protection pane, and then click Save on the Label pane.

Example 5: Label that encrypts content but doesn't restrict who can access it

This configuration has the advantage that you don't need to specify users, groups, or domains to protect an email or document. The content will still be encrypted and you can still specify usage rights, an expiry date, and offline access. Use this configuration only when you do not need to restrict who can open the protected document or email. More information about this setting

  1. On the Protection pane, make sure Azure (cloud key) is selected.

  2. Make sure Set permissions is selected, and then select Add permissions.

  3. On the Add permissions pane, on the Select from the list tab, select Add any authenticated users.

  4. Select the permissions you want, and click OK.

  5. Back on the Protection pane, configure settings for File Content Expiration and Allow offline access, if needed, and then click OK.

  6. On the Label pane, select Save.

Example 6: Label that applies "Just for me" protection

This configuration offers the opposite of secure collaboration for documents: With the exception of a super user, only the person who applies the label can open the protected content, without any restrictions. This configuration is often referred to as "Just for me" protection and is suitable when a user wants to save a file to any location and be assured that only they can open it.

The label configuration is deceptively simple:

  1. On the Protection pane, make sure Azure (cloud key) is selected.

  2. Select OK without selecting any users, or configuring any settings on this pane.

    Although you can configure settings for File Content Expiration and Allow offline access, when you do not specify users and their permissions, these access settings are not applicable. That's because the person who applies the protection is the Rights Management issuer for the content, and this role is exempt from these access restrictions.

  3. On the Label pane, select Save.
