Re: Outlook on Mac - Shared mailbox becomes no longer available.
Hi daniellebatt I already posted about how I worked around the issue. See above. Basically, don't use the flawed add shared mailbox option but use the add account and use the shared mailbox login credentials. I have a mix of both with the majority of shared mailboxes working as added shared mailboxes but just one that keeps dropping off. So it's the combination of that option and the particular mailbox... Hope it works for you...33KViews0likes1CommentRe: Outlook on Mac - Shared mailbox becomes no longer available.
I worked round the problem by removing the additional mailbox as a shared mailbox then added as a separate account. I always edit the credentials of my shared mailboxes much the same as a regular user account, so used these to add it as a new account. It’s worked ever since just fine. It shows slightly differently in the left-hand panel vs shared mailboxes but otherwise just fine. I used to work this way for all shared mailboxes I have before they added the ability to have as shared ones but seems there are issues with this. Hope that helps. Please let us know if that also works for you too. Thanks33KViews0likes0CommentsOutlook on Mac - Shared mailbox becomes no longer available.
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 mailto: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.38KViews1like12Comments
