Latest Message<\/th>\nTitle: Users may see an error when opening the side panel for quarantined messages within Microsoft Defender for Office 365<\/p>\n

User impact: Users may have seen an error when opening the side panel for quarantined messages within Microsoft Defender for Office 365.<\/p>\n

More info: Impact primarily manifested for on-premises or unified group mailboxes.<\/p>\n

Quarantined messages between the stated start and end times may not be available within Security Operations Center threat hunting experiences, including email entity, threat explorer, and advanced hunting. All actions and operations within the quarantine experience were still functional despite users encountering an error in the side panel display stating “Something went wrong. Primary and secondary data missing.” Users can leverage message tracking logs to review these messages as well.<\/p>\n

Final status: We’ve completed validation and deployment of the fix across all affected environments, and after monitoring the service, we’ve verified that this action successfully resolved the problem for new messages. Previous messages that were sent between the start and end time of this event will continue to display the error and won’t be present in the Security Operations Center hunting experiences. These messages can still be interacted with in quarantine despite this error message.<\/p>\n

Scope of impact: Any user may have been impacted when attempting to view quarantined messages within Microsoft Defender for Office 365.<\/p>\n

Start time: Friday, June 27, 2025, at 12:00 AM UTC<\/p>\n

End time: Thursday, July 31, 2025, at 3:50 PM UTC<\/p>\n

Root cause: A recent feature update had introduced a code issue resulting in impact to Defender quarantine experiences.<\/p>\n

Next steps:
– We’re investigating how the recent feature update introduced a code issue that impacted Defender quarantine experiences, in order to prevent this problem from happening again.<\/p>\n

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