Latest Message<\/th>\nTitle: Users may be unable to view Zero-hour auto purge (ZAP) email messages in Microsoft Defender for Office 365 quarantine<\/p>\n

User impact: Users may have been unable to view ZAP email messages in Microsoft Defender for Office 365 quarantine.<\/p>\n

More info: Users and admins may have seen no results when searching for ZAP email messages or affected ZAP email message recipients in quarantine. As a workaround, admins could view the ZAP email messages in Threat Explorer, but couldn\u2019t download or release the messages from quarantine.<\/p>\n

Final status: We completed deploying our solution to return the permissions needed to allow admins to view ZAP email messages and recipients on Wednesday, March 18, 2026, at 12:00 AM UTC. After an extended period of monitoring, we can confirm that this issue is fully resolved. <\/p>\n

Scope of impact: Your organization may have been affected by this event, and any user trying to view or download ZAP email messages in Microsoft Defender for Office 365 quarantine during the impact timeframe may have been impacted. <\/p>\n

Start time: Thursday, January 22, 2026, at 12:00 AM UTC<\/p>\n

End time: Wednesday, March 18, 2026, at 12:00 AM UTC <\/p>\n

Root cause: Specific permissions required to complete the process for admins to view ZAP email messages within quarantine weren\u2019t available due to a recent code change, resulting in impact.<\/p>\n

Next steps:
– To help prevent similar impacts in the future, we’re further reviewing our testing and validation processes prior to deployment of code changes.<\/p>\n

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