Problem: Room Finder works in OWA but in Outlook we get an error: We can't create the Room Finder right now.

↑ Room Finder error with Outlook365 Version 2208 semi-annual.
Solution: after research it appeared the error was linked to WebView2. I checked and this was already installed with the latest version, 111.0.1661.54. When I tried to install the standalone package I got an error saying it was already installed.
Based on a Reddit post I tried a reinstall via an admin Command Prompt:
"C:\Program Files (x86)\Microsoft\EdgeUpdate\MicrosoftEdgeUpdate.exe" /install appguid="{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}&appname=Microsoft%20Edge%20WebView&needsadmin=true&repairtype=windowsonlinerepair" /installsource taggedmi /silent
The command runs for about 10 seconds, without needing a reboot I restarted Outlook and could now see Room Finder in the Outlook client.

↑ Room Finder visible after WebView2 reinstall.
What was annoying about this was not everyone had the error so I wasn't going to push out a fix via SCCM to everyone if it wasn't needed. But there seems no way to check remotely if Room Finder is broken or to test WebView2.
