Latest Message<\/th>\nTitle: Admins may be unable to preview email messages in Microsoft Defender for Office 365<\/p>\n

User impact: Admins may have been unable to preview email messages in Microsoft Defender for Office 365.<\/p>\n

More info: When selecting the ‘Email preview’ button from the email summary flyout or from the Email Entity page, admins may have seen the following error message: “Message details couldn’t be found. When a message is soft deleted or hard deleted by the user or the admin, its details no longer exist in the mailbox or server”.<\/p>\n

Final status: Deployment of the fix is complete, and our tests have confirmed that email message previews in Microsoft Defender for Office 365 have been restored and impact is remediated.<\/p>\n

Scope of impact: This issue was impacting any admin who was attempting to preview email messages in Microsoft Defender for Office 365.<\/p>\n

Start time: Wednesday, December 20, 2023, at 8:58 AM UTC<\/p>\n

End time: Thursday, December 21, 2023, at 5:30 PM UTC<\/p>\n

Root cause: A recent configuration change to a component of infrastructure responsible for network authentication introduced a misconfiguration that prevented admins from previewing email messages in Microsoft Defender for Office 365, leading to impact.<\/p>\n

Next steps:
– We’re reviewing our Microsoft Defender for Office 365 update procedures pertaining to network authentication to prevent similar impact in future updates.<\/p>\n

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