Latest Message<\/th>\nTitle: Admins provisioning guest users in Exchange Online may see that duplicate objects are created<\/p>\n

User impact: Admins who provisioned guest users in Exchange Online may have seen that duplicate objects were created.<\/p>\n

More info: As a result of the duplicate objects which were provisioned, user email addressed to the newly created guest users may have failed to deliver.<\/p>\n

Final status: While we’ve confirmed that our fix has sufficiently saturated enough of the environment to remediate the issue, we’ve also disabled the offending feature portion of the update, which mitigated impact prior to the full deployment of our fix. We’ve confirmed with some affected users that the issue has been resolved. <\/p>\n

Scope of impact: Any admin who provisioned guest users in Exchange Online may have been impacted.<\/p>\n

Start time: Thursday, February 20, 2025, at 3:38 PM UTC<\/p>\n

End time: Thursday, February 27, 2025, at 1:00 PM UTC<\/p>\n

Root cause: A recent feature update to the data pathways leveraged to provision new guest users in Exchange Online exposed an error that caused some guest user data to be duplicated during provisioning, which led to impact.<\/p>\n

Next steps:
– We’re continuing to review our update processes so we can better identify similar errors during our testing and development cycles and avoid comparable impact in the future. <\/p>\n

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