Latest Message<\/th>\nTitle: Some admins may be unable to access and manage configured GDAP tenants in Microsoft Defender <\/p>\n

User impact: Admins may have been unable to access and manage configured GDAP tenants in Microsoft Defender. <\/p>\n

Final status: We’ve validated with internal telemetry that our fix was successful and the underlying issue is resolved. <\/p>\n

Scope of impact: Some admins that attempted to access configured GDAP-connected tenants in Microsoft Defender tenant views may have been impacted. <\/p>\n

Start time: Thursday, May 28, 2026, at 12:00 AM UTC <\/p>\n

End time: Monday, June 08, 2026, at 10:05 PM UTC <\/p>\n

Root cause: A recent service update to partner\u2013customer relationship functionality introduced a regression that was causing some GDAP-connected tenants to incorrectly return an empty tenant list, resulting in impact. <\/p>\n

Next steps:
– We’re further reviewing the service update to understand how the regression was introduced, and to understand what prevented it from being detected in our update testing and validation procedures, which will allow us to prevent similar issues in future updates. <\/p>\n

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