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 be unable to view ZAP email messages in Microsoft Defender for Office 365 quarantine.<\/p>\n

More info: Users and admins may see no results when searching for ZAP email messages or affected recipients of the ZAP email messages that were moved to quarantine.
As a workaround, admins can view the ZAP email messages in Threat Explorer, but won\u2019t be able to download or release the messages from quarantine.<\/p>\n

Current status: We\u2019re continuing to deploy our solution throughout the impacted service infrastructure and have reached 50 percent saturation. We expect the deployment will be complete by our next scheduled update, after which point we will monitor to confirm the issue is fully resolved. <\/p>\n

Scope of impact: Your organization may be affected by this event, and any user trying to view or download ZAP email messages in Microsoft Defender for Office 365 quarantine may be impacted. This information may be updated as our investigation continues.<\/p>\n

Start time: Thursday, January 22, 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 aren\u2019t available due to a recent code change, resulting in impact.<\/p>\n

Next update by: Friday, March 20, 2026, at 10:00 PM UTC<\/td>\n<\/tr>\n
