getting mail from Exchange/Outlook

[Steve Kleene <skdeb@syrano.acb.uc.edu>]

My employer is forcing me to shut down my long-time Linux mail server.  I
have no choice in the matter.

My employer uses Microsoft Exchange/Outlook for mail.  They have an Outlook
Web App (OWA) that I can access from Firefox, but as far as I can tell you
cannot save a file to the local disk with OWA.  That makes OWA pretty
useless.  The documentation, if it can be believed, says that I can access
Outlook with POP3 and IMAP4 programs including Thunderbird.

If any of you have experience and/or advice with this problem, I'd be
grateful to hear it.
