it's been a while since I dealt with that, I mind you Exchange Serve might have changed since the 2003 version, but see if you can make a .pst file for Outlook access off-site. A .pst is the file created when you use Outlook as a stand-alone product. You would do this from Outlook.
As I remember, you might not be able to get all of the info, (appointments, notes, etc), you had on the Exchange Server, but you can get your emails and, I believe, your contacts, as well.
