WVD Outlook Calendar/Contact search not working

[Jared_Nickerson]

Recently our WVD (classic) environment started having an issue with Outlook search not working for calendar or contacts.  After a bit of troubleshooting and no luck, I decided to just rebuild a WVD ARM environment since we were not able do run updates in the old environment anyway.

Long story short, got the new environment up, same issue.

Windows 10 2004 marketplace image (without Office)

Office 365 multi-user installed from deployment tool xml

Outlook Cached mode enabled, 3 months (also tried 1 year)

Single pooled VM host, no FSLOGIX

The strange thing is that searching the inbox works fine.  Only calendar and contacts (searching contacts from the mail tab works, but not the contacts tab) fail to find anything.  No option to search online either, just "no results"

Any help would be appreciated.

@Jared_Nickerson Seeing the same issue on an FSLogix deployment, with Windows on 1909 still.

Some users search, ones that don't show an unavailable location and 0 items in the Search Index.

Same issue with one of our clients. Microsoft, please step in.

I had a ticket open for months, went through multiple departments, and finally ... no resolution.  We switched to online mode for now but it's not a real fix.
