I recently needed to wipe M365 from my Macbook and setup from scratch.
On setting up Outlook, realised they had implemented the ability to add shared mailboxes, just thru the main logged in user, via delegated permissions. Happy days. My previous setup, created a few years back, had the shared mailboxes added as regular mailboxes but as I say, all that setup has now changed.
I've got 3 shared mailboxes I added and all worked fine. One of them however (for support@) keeps coming up saying "This shared mailbox is no longer available". It doesn't receive new emails, etc and is in limbo. Closing Outlook and opening again gets it working, for a while buy the not available comes back after variable times; sometimes few minutes up to days. Other 2 shared mailboxes, I have included, work fine.
I'm using Outlook for Mac, Version 16.74 (23050300), the latest at this point. It was happening with the last couple of versions too.
Anyone else having this?
Any ideas how to resolve or diagnose?
Thanks,
Alan Wright.

We are also experiencing this on one of our Macs. So far no resolution. We've tried everything except a system reset. @wrighta16

@wrighta16 would be interested to know if you found a solution for this? Having the same issue after trying the 'New Outlook'. Lagacy version still has the same problem now

We are having the same trouble with 1 shared mailbox which is configured on different systems.
3 Mac's (MacOS 13.4, 13.3.1 and 11.7.7) have these problems of being unavailable after a certain amount of time.
1 Mac the same shared mailbox is working just fine. (MacOS 13.4)
All Macs have the latest Office (16.73)
No clue how to solve this.
So hoping someone has a solution.
