Issue Status: RESOLVED
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.
Final Update: 24/01/2025 08:31:00 AM – Microsoft have successfully deployed the fix to the affected infrastructure, and confirmed after a period of monitoring that impact has been remediated.
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.
Next steps: Microsoft are reviewing their update procedures to better identify similar issues during their development and testing cycles.
