Search works from OWA \ Mobiles but in desktop Outlook clients i'm getting numerous reports of 'We're having trouble fetching results from the server...' with an option to select 'let's look on your computer instead'
Health checker has no issues.
- Server 2019 with latest SU applied
Issue is on Outlook 21 \ o365 outlook clients on perm exchange server.
Issue is only with Outlook clients set to use Cached Mode \ change to Online and search works perfectly
Exchange shell Bigfunnel commands also report nothing out of the ordinary aka everything is indexed.
- Download Domains is setup but we dont use OWA so was happy to roll this out.
A workaround until this is sortedd is to disable server assisted search, once it's fixed you can roll back to 0.

• Key: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Search
• Value name: DisableServerAssistedSearch
• Value type: REG_DWORD
• Value: 1
