When users search in Outlook for Windows selecting specific queries from the Suggested Searches they see “No results”. This is affecting users working with non-English versions of Windows and M365 Apps. 

Not all Suggested Searches queries will fail. We are currently aware of the failures below, but other languages might be affected:


Invalid suggested query: an:”” 
Working query: bis:”” 


Invalid suggested query: 보낸사람:”” 
Working query: 시작:”” 


Invalid suggested query: откого:”” 
Working query: от:”” 

Invalid suggested query: имяполучателя:”” 
Working query: кому:””

No results in Outlook using suggested searches


The Outlook Team fixed this issue in the service, and it completed rolling out April 17, 2023.  

If you used any of the workarounds below you can now revert those steps and search normally:

  • Users can manually modify the invalid query to have proper search results by using the queries above.

  • Users can replace the localized query (in local language) and replace it by the English equivalent.

  • Temporarily disable Server Assisted Search, which would fallback to the legacy Windows Desktop Search, with the following registry key:

    DWORD: DisableServerAssistedSearch 
    Value: 1

Note: If you used the DisableServerAssistedSearch policy registry key, remember to remove the registry key now that the fix has been implemented.
