M365 Groups dumped in Outlook for Windows?

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

As you can see the *.nst File is here. It is the offline Cache for M365 Groups - similar to the *.ost for the Mailbox.

Another Computer with current Channel Preview

Missing the M365 Groups in the Folders

The cached Files are stored in C:\Users\<Username>\AppData\Local\Microsoft\Outlook.
But here i only see *.ost Files - no *.nst available

In Outlook on the Web the Groups are still there

Not long ago, Microsoft have enabled Folders and Rules for M365 Groups.

Looks to me that Outlook for Windows will dump the Groups. What do you think?
