Hi All,
Yesterday i stumbled across something odd. Did not see the M365 Groups in Outlook for Windows anymore. They seem to be gone in the newest Version.
Let’s start at the beginning. Office in the Current Channel
Outlook Profile is set up with Cached Mode (without Chached Mode you don’t see the M365 Groups either).
As you can see the Groups are listed here
The cached Files are stored in C:\Users<Username>\AppData\Local\Microsoft\Outlook
Hi All,

https://security.microsoft.com/securitysettings/userSubmission
I’ve enabled that a while ago.
As you can see the Reporting Mailbox receives all types:
