Final status: We’ve confirmed that the fix has been fully deployed and that impact is resolved.
Scope of impact: Users attempting to remove users from the contact list within Outlook on the web may have been impacted.<\/p>\n

Start time: Monday, August 4, 2025, at 6:32 PM UTC<\/p>\n

End time: Wednesday, December 17, 2025, at 12:00 AM UTC<\/p>\n

Root cause: The Microsoft Entra ID contacts that were removed from active directory contained an X500 smtp address assigned to them, which prevented users from deleting the contacts from the contact list within Outlook on the web.<\/p>\n

Next steps:
– We’re reviewing our Microsoft Entra ID contacts procedures to help prevent this problem from happening again.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
