As communicated in: MC252690, we wanted to share that on or around May 14, 2021, Microsoft Lists now supports the Conditional Access (CA) grant access control, “Require approved client app”, like other Microsoft 365 apps, such as SharePoint.
If you are using a CA policy that only leverages the “Require approved client app” grant access control, Microsoft Lists will be considered one of the approved apps after this date. You must enable Intune APP with Microsoft Lists to ensure it meets the full data protection needs of your organization. However, we strongly recommend that you update your CA policy to take advantage of the “Require app protection policy” grant access control. For more information on the recommended policy configuration, see Scenario 1 in How to: Require app protection policy and an approved client app for cloud app access with Condition....
If you are not utilizing APP, CA, or either grant access control, then no action is needed.
Note: If you previously used the bundle ID (com.microsoft.splists) to add Lists manually, the bundle ID is hidden and the app is now listed as a selected app within the public apps section of the policy. If you attempt to create a new policy and try to add the bundle ID manually, the MEM admin center will notify you to use the public app instead.
