Connect Dynamics 365 (on-premises) to Exchange Online

Applies To: Dynamics 365 (on-premises), Dynamics CRM 2016

This topic describes how to configure server-based authentication between Dynamics 365 (on-premises) and Exchange Online. The diagram below illustrates the communication between Dynamics 365 (on-premises), Azure Active Directory, and Exchange Online.

Dynamics 365 on-premises and Exchange Online

Permissions required

Microsoft Dynamics 365

  • System Administrator security role.

  • If you are using a self-signed certificate for evaluation purposes, you must have local Administrators group membership on the computer where Microsoft Dynamics 365 Server is running.

Exchange Online

  • Office 365 Global Administrators membership. This is required for administrative-level access to the Office 365 subscription and to run the Microsoft AzurePowerShell cmdlets.

Important

In this deployment, the Dynamics 365 administrator can approve mailboxes.

Set up server-based authentication with Microsoft Dynamics 365 and Exchange Online

Follow the steps in the order provided to set up Dynamics 365 (on-premises) with Exchange Online.

Important

  • The steps described here must be completed in the order provided. If a task is not completed, such as a Windows PowerShell command that returns an error message, the issue must be resolved before you continue to the next command, task, or step.

Verify prerequisites

Before you configure Dynamics 365 (on-premises) and Exchange Online for server-based authentication, the following prerequisites must be met:

  • The Dynamics 365 (on-premises) deployment must already be configured and available through the Internet. More information: Configure IFD for Microsoft Dynamics 365

  • Microsoft Dynamics 365 Hybrid Connector. The Microsoft Dynamics 365 Hybrid Connector is a free connector that lets you use server-based authentication with Microsoft Dynamics 365 (on-premises) and Exchange Online. More information: Microsoft Dynamics 365 Hybrid Connector

  • An x509 digital certificate issued by a trusted certificate authority that will be used to authenticate between Dynamics 365 (on-premises) and Exchange Online. If you are evaluating server-based authentication, you can use a self-signed certificate.

The following software features are required to run the Windows PowerShell cmdlets described in this topic:

Set up server-based authentication

  1. On the Microsoft Dynamics 365 Server where the deployment tools server role is running, start the Azure Active Directory Module for Windows PowerShell.

    Important

    The computer where you run the following PowerShell commands must have the prerequisite software features described earlier in Verify prerequisites.

  2. Prepare the certificate. Replace contoso\adminstrator with your domain\account.

    $CertificateScriptWithCommand = “.\CertificateReconfiguration.ps1 -certificateFile c:\Personalcertfile.pfx -password personal_certfile_password -updateCrm -certificateType S2STokenIssuer -serviceAccount contoso\administrator -storeFindType FindBySubjectDistinguishedName”
    
    Invoke-Expression -command $CertificateScriptWithCommand
    
  3. Prepare the Windows PowerShell session.

    The following cmdlets enable the computer to receive remote commands and add Office 365 modules to the Windows PowerShell session. For more information about these cmdlets see Windows PowerShell Core Cmdlets.

    Enable-PSRemoting -force
    New-PSSession
    Import-Module MSOnline -force
    Import-Module MSOnlineExtended -force
    
  4. Connect to Office 365.

    When you run the Connect-MsolService command, you must provide a valid Microsoft account that has Office 365 Global Administrator membership for the Exchange Online license that is required.

    For detailed information about each of the Azure Active Directory PowerShell commands listed here, see MSDN: Manage Azure AD using Windows PowerShell.

    $msolcred = get-credential
    connect-msolservice -credential $msolcred
    
  5. Set the certificate.

    $STSCertificate = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2 -ArgumentList c:\Personalcertfile.pfx, personal_certfile_password
    $PFXCertificateBin = $STSCertificate.GetRawCertData()
    $Certificate = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2
    $Certificate.Import(“c:\Personalcertfile.cer”)
    $CERCertificateBin = $Certificate.GetRawCertData()
    $CredentialValue = [System.Convert]::ToBase64String($CERCertificateBin)
    
  6. Set the Azure Active Directory Service Principal Name (SPN) in Exchange Online.

    Replace *.contoso.com with the domain name where Microsoft Dynamics 365 Server is located.

    $RootDomain = “*.contoso.com”
    $CRMAppId = "00000007-0000-0000-c000-000000000000" 
    New-MsolServicePrincipalCredential -AppPrincipalId $CRMAppId -Type asymmetric -Usage Verify -Value $CredentialValue
    $CRM = Get-MsolServicePrincipal -AppPrincipalId $CRMAppId
    $ServicePrincipalName = $CRM.ServicePrincipalNames
    $ServicePrincipalName.Remove("$CRMAppId/$RootDomain")
    $ServicePrincipalName.Add("$CRMAppId/$RootDomain")
    Set-MsolServicePrincipal -AppPrincipalId $CRMAppId -ServicePrincipalNames $ServicePrincipalName
    
  7. Configure the Microsoft Dynamics 365 Server for server-based authentication with Exchange Online.

    Add-PSSnapin Microsoft.Crm.PowerShell 
    $setting = New-Object "Microsoft.Xrm.Sdk.Deployment.ConfigurationEntity"
    $setting.LogicalName = "ServerSettings"
    $setting.Attributes = New-Object "Microsoft.Xrm.Sdk.Deployment.AttributeCollection"
    $attribute1 = New-Object "System.Collections.Generic.KeyValuePair[String, Object]" ("S2SDefaultAuthorizationServerPrincipalId", "00000001-0000-0000-c000-000000000000")
    $setting.Attributes.Add($attribute1)
    $attribute2 = New-Object "System.Collections.Generic.KeyValuePair[String, Object]" ("S2SDefaultAuthorizationServerMetadataUrl", "https://accounts.accesscontrol.windows.net/metadata/json/1")
    $setting.Attributes.Add($attribute2)
    Set-CrmAdvancedSetting -Entity $setting
    

Set the Exchange Online tenant ID

  1. In the Azure Active Directory module for Windows PowerShell shell, run the following commands.

    $CRMContextId = (Get-MsolCompanyInformation).ObjectID
    $CRMContextId
    
  2. Copy the GUID that is displayed to the clipboard.

  3. Update S2STenantId for the organization by running these commands, where OrganizationName is the unique name of the organization.

    $organizationName = “OrganizationName”
    $CRMContextId = “ExchangeOnlineTenantId”
    $orgInfo = Get-CrmOrganization -Name $organizationName
    $ID = $orgInfo.id 
    
     if($ID)
         {
           Set-CrmAdvancedSetting -ID $orgInfo.ID -configurationEntityName "Organization" -setting "S2STenantId" -value $CRMContextId
         }

      Note

      If your users primarily use Dynamics 365 for Outlook on their desktop computers, Microsoft Dynamics 365 for Outlook might be a better choice.

    If you leave the Email processing form unapproved user and queues at the default values (selected), you will need to approve emails and queues for user mailboxes as directed below in Approve Email.

    System Settings for server-side synchronization

  3. Click OK.

Configure mailboxes

To set mailboxes to use the default profile, you must first set the Server Profile and the delivery method for email, appointments, contacts, and tasks.

In addition to administrator permissions, you must have Read and Write privileges on the Mailbox entity to set the delivery method for the mailbox.

Select one of the following methods:

Set mailboxes to the default profile

  1. Go to Settings > Email Configuration > Mailboxes.

  2. Click Active Mailboxes.

  3. Select all the mailboxes that you want to associate with the Exchange Server profile you created, click Apply Default Email Settings, verify the settings, and then click OK.

    Apply default email settings

    By default, the mailbox configuration is tested and the mailboxes are enabled when you click OK.

Edit mailboxes to set the profile and delivery methods

  1. Go to Settings > Email Configuration > Mailboxes.

  2. Click Active Mailboxes.

  3. Select the mailboxes that you want to configure, and then click Edit.

  4. In the Change Multiple Records form, under Synchronization Method, set Server Profile to the Exchange Server profile you created earlier.

  5. Set Incoming and OutgoingEmail to Server-Side Synchronization or Email Router.

  6. Set Appointments, Contacts, and Tasks to Server-Side Synchronization.

    Note

    If your users primarily use Dynamics 365 for Outlook on their desktop computers, Microsoft Dynamics 365 for Outlook might be a better choice.

  7. Click Change.

Approve email

You need to approve each user mailbox or queue before that mailbox can process email.

  1. Go to Settings > Email Configuration > Mailboxes.

  2. Click Active Mailboxes.

  3. Select the mailboxes that you want to approve, and then click More Commands () > Approve Email.

  4. Click OK.

Test configuration of mailboxes

  1. Go to Settings > Email Configuration > Mailboxes.

  2. Click Active Mailboxes.

  3. Select the mailboxes you want to test, and then click Test & Enable Mailboxes.

    This tests the incoming and outgoing email configuration of the selected mailboxes and enables them for email processing. If an error occurs in a mailbox, an alert is shown on the Alerts wall of the mailbox and the profile owner. Depending on the nature of the error, Microsoft Dynamics 365 tries to process the email again after some time or disables the mailbox for email processing.

    The result of the email configuration test is displayed in the Incoming Email Status, Outgoing Email Status, and Appointments, Contacts, and Tasks Status fields of a mailbox record. An alert is also generated when the configuration is successfully completed for a mailbox. This alert is shown to the mailbox owner.

Tip

If you’re unable to synchronize contacts, appointments, and tasks for a mailbox, you may want to select the Sync items with Exchange from this Dynamics 365 org only, even if Exchange was set to sync with a different org check box. Read more about this check box.

Test email configuration for all mailboxes associated with an email server profile

  1. Go to Settings > Email Configuration > Email Server Profiles.

  2. Select the profile you created, and then click Test & Enable Mailboxes.

    When you test the email configuration, an asynchronous job runs in the background. It may take a few minutes for the test to be completed. Microsoft Dynamics 365 tests the email configuration of all the mailboxes associated with the Exchange Server profile. For the mailboxes configured with server-side synchronization for synchronizing appointments, tasks, and contacts, it also checks to make sure they’re configured properly.

Tip

If you’re unable to synchronize contacts, appointments, and tasks for a mailbox, you may want to select the Sync items with Exchange from this Dynamics 365 org only, even if Exchange was set to sync with a different org check box. Read more about this check box.
