I have two accountants that can't download new emails. Both have "mounted" a shared Exchange 2007 mailbox, along with their personal mailbox. If I remove the shared Exchange mailbox, their mail starts downloading again. If I added back the shared mailbox, they can't download email.
When I say "mounted", I'm referring to Tools, Account Settings, double click on the name, More settings, advanced, click "add".
This started happening this week. There have been no changes on my Exchange server.
Any idea why a shared mailbox would stop mail from downloading. I mount accounts this way all the time. Only these two people have this issue.
