Microsoft is working on fully mitigating issues causing Outlook on the web and SharePoint Online users to experience delays or failures when searching.

Tracked under EX1063763 in the Microsoft 365 Admin Center, the issues are caused by infrastructure components responsible for processing users’ search requests that perform below acceptable performance thresholds.

The company first acknowledged this Exchange Online incident at 05:21 UTC, with the latest update published at 08:22 saying that a recently deployed fix should provide relief while Redmond’s engineers check if further optimizations are required to fully mitigate the search issues.
