Hello all,
I had users that have been accessing shared mailboxes from their outlook clients for weeks with no issues. All of a sudden, whenever they try to access the shared mailboxes, the cursor spinds until it times out and then brings up a dialog box saying:
The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance.
Our Exchange server is E365, so it is definately up. The permissions on the shared mailbox are correct, because you can open the shared mailbox using OWA.
Any ideas why the long term function of "open these additional mailboxes" under the main account would no longer function?
Thank you!
