Some of you may wonder why things are set up the way the are in my page, Using Outlook/Exchange for calendar only, while keeping e-mail in Thunderbird. It is because mail addressed to username@wfu.edu is handled differently depending on the sender and recipient.
That is why IS tells those going all Outlook/Exchange to set up forwarding of non-Exchange mail, and that is why using Thunderbird requires grabbing mail from two different servers.
