Latest Message<\/th>\nTitle: Some admins may be unable to remove blocked users from the Restricted entities page in Microsoft 365 suite<\/p>\n

User impact: Admins may be unable to remove blocked users from the Restricted entities page in Microsoft 365 suite.<\/p>\n

More info: Affected admins can\u2019t remove Restricted entities from the Microsoft Defender XDR portal, Exchange Online admin center, or PowerShell.<\/p>\n

Current status: We identified that our previous fix for the issue could have caused additional service degradation. We reverted the fix, causing this impact to reoccur and are now rolling back to a previously known stable build to remediate the impact. Affected users should experience relief as the rollback progresses.<\/p>\n

Scope of impact: Admins removing blocked users from the Restricted Entities page in Microsoft 365 suite may be impacted.<\/p>\n

Start time: Saturday, May 2, 2026, at 12:15 AM UTC<\/p>\n

Root cause: A modification made to a previous change is resulting in admins potentially receiving an error when removing a blocked user from the Restricted entities page in Microsoft 365 suite.<\/p>\n
