Title: Users’ “Groups I Own” membership options may not show the display names as expected in the Exchange admin center (EAC)
User impact: Users’ “Groups I Own” membership options may have not shown the display names as expected in the EAC.
Final status: We’ve confirmed with affected users that the fix deployment has succeeded in remediating the impact.
Scope of impact: Any user attempting to see the display names within groups they own from the “Groups I Own” membership options in the EAC may have been impacted.
Start time: Monday, October 2, 2023, at 4:22 PM UTC
End time: Friday, October 13, 2023, at 9:30 AM UTC
Root cause: A code change to the EAC prevented the display name from displaying correctly in the “Groups I Own” membership options, preventing users from seeing the members of the groups they own.
Next steps:
– We’re reviewing this code change to the EAC to understand why it caused the impact and to assess how this impact scenario was missed in our updating testing phase, which will bolster our testing and validation procedures and prevent similar impact from reoccurring.
This is the final update for the event.
