Issue Description: Users’ searches may fail and provide no results in the Outlook desktop client and Outlook on the web.

Current Update: 3/01/2025 09:13:00 AM – The development of Microsoft’s code fix to trigger their automated recovery service to restart infrastructure supporting search functionality and clear any errors is complete. They are preparing their deployment procedures to implement the fix by the end of January 2025 and will closely monitor the progress.

Scope of impact: Some users attempting to perform searches in the Outlook desktop client and Outlook on the web may be intermittently impacted.

Root cause: A service memory issue is causing the infrastructure responsible for facilitating core service search to intermittently go into an unresponsive state.
