User impact: Users may be unable to edit their OneDrive for Business content as they are in a read-only state.

More info: The error message states that “You can’t edit your files because your license to use OneDrive ended over a month ago.”

Admins can remove the read-only lock by following the instructions on this link via PowerShell: learn.microsoft.com/en-us/sharepoint/manage-lock-status. Please note: the read-only notification will remain visible until full mitigation has been completed next week, however no archiving actions will take place.

Admins should permanently change configurations from their unsupported states as described here: learn.microsoft.com/en-us/sharepoint/manage-user-profiles#add-and-remove-admins-for-a-users-onedrive.

Current status: Our rollback of read-only sites is progressing as expected in a thorough and secure pace for our previously identified use cases. While we continue our mitigation efforts, we strongly recommend admins to take prompt action and perform the self-mitigation steps outlined in our “More Info” section as our changes may not address every unique configuration of OneDrive owners who have been changed from the correct Entra ID owner. We’ll continue rollbacks and provide another update on Wednesday, February 26, 2025, at 10:00 PM UTC.

Scope of impact: Any organization may be affected by this event, and some users’ OneDrive for Business content may be in read-only mode.

Root cause: A recent policy enforcement rollout is unintentionally resulting in read-only mode of OneDrive for Business when admins have modified their users OneDrive for Business owners from a dedicated person to a group or service account which is a strictly unsupported state.
