Capabilities of Basic Mobility and Security
Basic Mobility and Security can help you secure and manage mobile devices like iPhones, iPads, Androids, and Windows Phones used by licensed Microsoft 365 users in your organization. You can create mobile device management policies with settings that can help control access to your organization’s Microsoft 365 email and documents for supported mobile devices and apps. If a device is lost or stolen, you can remotely wipe the device to remove sensitive organizational information.
Supported operating systems
Follow the Microsoft Intune operating systems guide for the minimum supported operating systems for devices by Basic Mobility and Security. For more info, see Intune supported operating systems.
You can use Basic Mobility and Security to secure and manage the following devices.
- iOS
- Android (including Samsung Knox)1
- Windows2, 3
1After June 2020, Android versions later than 9 can't manage password settings except on Samsung Knox devices.
2Access control for Windows 8.1 RT devices is limited to Exchange ActiveSync.
3Access control for Windows 10 requires a subscription that includes Microsoft Entra ID P1 or P2 and the device needs to be joined to Microsoft Entra ID.
Note
Devices already enrolled with earlier OS versions continue to function although the capabilities might change without notice.
If people in your organization use mobile devices that aren't supported by Basic Mobility and Security, you may want to block Exchange ActiveSync app access to Microsoft 365 email for those devices, to help make your organization's data more secure. For steps to block Exchange ActiveSync, see Manage device access settings in Basic Mobility and Security.
Access control for Microsoft 365 email and documents
The supported apps for the different types of mobile devices in the following table prompt users to enroll in Basic Mobility and Security 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 Microsoft 365 resources in these apps, or they might have access but Microsoft 365 reports a policy violation.
| Product | iOS | Android |
|---|---|---|
| Exchange Exchange ActiveSync includes built-in email and third-party apps, like TouchDown, that use Exchange ActiveSync Version 14.1 or later. | ||
| Apps in Microsoft 365 and OneDrive for Business | Outlook OneDrive Word Excel PowerPoint |
On phones and tablets: Outlook OneDrive Word Excel PowerPoint On phones only: Microsoft 365 mobile |
Note
- Support for iOS 10.0 and later versions includes iPhone and iPad devices.
- Management of BlackBerry OS devices isn’t supported by Basic Security and Mobility. Use BlackBerry Business Cloud Services (BBCS) from BlackBerry to manage BlackBerry OS devices. Blackberry devices running Android OS are supported as standard Android devices
- Users won’t be prompted to enroll and won’t be blocked or reported for policy violation if they use the mobile browser to access Microsoft 365 SharePoint sites, documents in Microsoft 365 on the web, or email in Outlook Web App.
The following diagram shows what happens when a user with a new device signs in to an app that supports access control with Basic Mobility and Security. The user is blocked from accessing Microsoft 365 resources in the app until they enroll their device.
Note
Policies and access rules created in Basic Mobility and Security for Microsoft 365 Business Standard will override Exchange ActiveSync mobile device mailbox policies and device access rules created in the Exchange admin center. After a device is enrolled in Basic Mobility and Security for Microsoft 365 Business Standard, 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
If you create a policy to block access with certain settings turned on, users are blocked from accessing Microsoft 365 resources when using a supported app that is listed in Access control for Microsoft 365 email and documents.
The settings that can block users from accessing Microsoft 365 resources are in these sections:
Security
Encryption
Jail broken
Managed email profile
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 Basic Mobility and Security. They are blocked from accessing Microsoft 365 resources in the app until their device complies with the security setting.
The following sections list the policy settings you can use to help secure and manage mobile devices that connect to your Microsoft 365 organization resources.
