I cannot add a Department mailbox in Outlook.
It has been noticed that some shared mailboxes were not able to be added to Outlook by entering the email address as Department@MissouriState.edu. After troubleshooting the issue, we see that it looks like adding them as Department@Live.MissouriState.edu works. We're unable to find any rhyme or reason as to which mailboxes require this. Not all mailboxes do this, and it’s rare that it happens, but it’s worth trying if you run into this issue.
I get the error message "Outlook is using an old copy of your Outlook data file (.ost). Exit Outlook, delete the file, and restart Outlook. A new file will be automatically created the next time you initiate a send/receive."
