Dear CAS,

I would like to let you know that there is an ongoing service incident affecting email search, where some users are unable to search for email in Outlook desktop and Outlook on the web, which aligns with the behavior you are reporting. Microsoft engineers are aware of this issue and are actively working to roll out a fix as soon as possible, so no troubleshooting is needed on your side for now.

For further details, please contact your organization's IT administrator. They can verify the status of the service incident for your tenant and submit a technical support ticket to Microsoft to prioritize a fix. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support

I am sorry for the inconvenience this has caused. If you have any additional questions or further information to share, please don't hesitate to let me know.

Where is the service health advisory or reference to the incident?

Dear Thomas,

There is no public service health advisory I can point you to for this at the moment. The issue is still under investigation, and Microsoft is currently collecting data on it. If you would like confirmation, the best route is to have your IT admin submit a service request with Microsoft. Support can check internally and confirm whether your tenant is affected.

I hope this helps. Please let me know if you need anything else.

@Thomas Webb I might be wrong, but I suspect the issue is related to Issue ID CW1470765 [Copilot issue and indexing servers back] - potentially affecting outlook search.

Some users attempting to search for Exchange Online email in the Outlook desktop client and Outlook on the web may be impacted. This information may be updated as our investigation continues.
