View or configure Outlook on the web mailbox policy properties
You can configure mailbox policies in Exchange Server for Outlook on the web through the Exchange admin center (EAC) or Exchange Management Shell. After you create an Outlook on the web mailbox policy, you can then configure a variety of options to control the features available to users in Outlook on the web. For example, you can enable or disable Inbox rules or create a list of allowed file types for attachments.

Use the EAC to view or configure Outlook on the web mailbox policies
In the EAC, click Permissions > Outlook Web App policies.
In the result pane, click to select the mailbox policy you want to view or configure.
On the General tab, you can view and edit the name of the policy.
On the Features tab, use the check boxes to enable or disable features. By default, the most common features are displayed. To see all features that can be enabled or disabled, click More options.
Features settings for Outlook on the web mailbox policies override Outlook on the web virtual directory settings. You can change segmentation settings for individual users by using the Set-CASMailbox cmdlet in the Exchange Management Shell.
The option to enable or disable the standard version of Outlook on the web by using the Premium client check box has been deprecated and will be removed from the settings. The standard version of Outlook on the web is always enabled.
On the File Access tab, use the check boxes to configure the file access and viewing options for users. File access lets a user open or view the contents of files attached to an email message.
File access can be controlled based on whether a user has signed in on a public or private computer. The option for users to select private computer access or public computer access is available only when you're using forms-based authentication. All other forms of authentication default to private computer access.
Direct file access: Select this check box if you want to enable direct file access. Direct file access lets users open files attached to email messages.
WebReady Document Viewing: Select this check box if you want to enable supported documents to be converted to HTML and displayed in a web browser.
Force WebReady Document Viewing when a converter is available: Select this check box if you want to force documents to be converted to HTML and displayed in a web browser before users can open them in the viewing application. Documents can be opened in the viewing application only if direct file access has been enabled.
On the Offline access tab, use the option buttons to configure offline access availability.
Click Save to update the policy.
