Access control for Office 365 email and documents

The supported apps for the different types of mobile devices in the following table will prompt users to enroll in MDM for Office 365 where there is a new mobile device management policy that applies to a user’s device and the user hasn’t previously enrolled the device. If a user’s device doesn’t comply with a policy, depending on how you set the policy up, a user might be blocked from accessing Office 365 resources in these apps, or they might have access but Office 365 will report a policy violation.

The following diagram shows what happens when a user with a new device signs in to an app that supports access control with MDM for Office 365. The user is blocked from accessing Office 365 resources in the app until they enroll their device.

Note: Policies and access rules created in MDM for Office 365 will override Exchange ActiveSync mobile device mailbox policies and device access rules created in the Exchange admin center. After a device is enrolled in MDM for Office 365, any Exchange ActiveSync mobile device mailbox policy or device access rule applied to the device will be ignored. To learn more about Exchange ActiveSync, see Exchange ActiveSync in Exchange Online.

Policy settings for mobile devices

Exchange

If you create a policy to block access with certain settings turned on, users will be blocked from accessing Office 365 resources when using a supported app that is listed in Access control for Office 365 email and documents. The settings that can block users from accessing Office 365 resources are in these sections:

For example, the following diagram shows what happens when a user with an enrolled device isn’t compliant with a security setting in a mobile device management policy that applies to their device. The user signs in to an app that supports access control with MDM for Office 365. They are blocked from accessing Office 365 resources in the app until their device complies with the security setting.
