Can't open one shared mailbox; Outlook 2010 or 2016, Exchange 2016
We have an Exchange '16 server. There are some mailboxes with @defaultdomain.com primary addresses. My account has full permission to all of those mailboxes, and my Outlook (whether '10 or '16) will open, manage, and send from all of them. There is one mailbox with @differentdomain.com as its primary address.
The workstation at my office runs Office 2010, and is on the same domain as the Exchange server and is connected to it locally, the @differentdomain.com mailbox opens fine.
My laptop is not on the domain and also runs Office 2010, and it will not open the @differentdomain.com mailbox. It doesn't matter if it is connected locally via ethernet, locally via wireless, or remotely. It gives: "Cannot expand the folder. The set of folders cannot be opened. The attempt to log on to microsoft exchange has failed."
My workstation at home behaves the same as my laptop; it's running Office 2016.
I tried adding an @defaultdomain.com address to the uncooperative mailbox and that did not help.
If I create a separate profile in Outlook and have it connect to just the uncooperative mailbox, it opens fine. But I would like to have the uncooperative mailbox open within my default profile.
When I try to open the mailbox by adding it inside of the mail settings, I get an error that says something like "you have tried to open more items than your Exchange administrator will allow", and then none of my Outlooks on any of my devices (not just the one that I tried to add the mailbox) can connect until I remove the extra mailbox from my Outlook and restart the Exchange services.
This is an issue that's been around for a while--since we upgraded from Exchange '10 to Exchange '16 a while back, if memory serves. I seem to recall it being because the uncooperative mailbox has a different domain as its primary email address, and that it was specifically unfixable because of that, but that's the extent of my recollection.
Can this be resolved? If so, how?
