Latest Message<\/th>\nTitle: Admins may not be able to search for Microsoft 365 Copilot Chat messages using Microsoft Purview eDiscovery searches<\/p>\n

User impact: Admins may not be able to search for Copilot Chat messages using eDiscovery searches.<\/p>\n

Current status: Based on the current rate of saturation from our fix deployment, we anticipate it will complete, remediating impact for all admins, by our next scheduled communication update on Friday, March 27, 2026, at 1:30 AM UTC.<\/p>\n

Scope of impact: Admins performing eDiscovery searches that should contain Copilot Chat messages may be impacted by this event.<\/p>\n

Start time: Friday, February 13, 2026, at 7:20 PM UTC<\/p>\n

Estimated time to resolve: We anticipate the deployment of our fix will complete by Friday, March 27, 2026, at 1:30 AM UTC.<\/p>\n

Root cause: A latent code error is preventing some metadata from being indexed as expected, which is resulting in impact.<\/p>\n

Next update by: Friday, March 27, 2026, at 1:30 AM UTC<\/td>\n<\/tr>\n
