Issue Status: ONGOING

Issue Description: Users within Microsoft 365 groups without an owner may be unable to take ownership

More info: Users within a group without an owner are sent an email message asking if they’d like to take ownership.

A 500 HTTP error response is presented if a user selects “yes” or “no” within the message.

As a workaround users can reach out to admins to manually set the owner of the groups.

Current Update: 21/01/2025 13:25:00 PM – Microsoft have deployed the fix to approximately 20% of the affected environment. As the fix progresses, users will begin to experience mitigation relief. They’re anticipating the deployment will be complete by Friday, January 24, 2025.

Scope of impact: Your organization is affected by this event, and impact is specific to users in Microsoft 365 groups without an owner and receive an ownership request.

Root cause: A regression within a recent update, intended to improve the user experience, is inadvertently causing a dependency exception issue and impact.
