When you view your mail from another computer using an IMAP client, you'll see the same mail in the same folders. Eudora users won't have to relearn an interface because Eudora works with IMAP servers just as it does with POP servers. In many respects, Exchange functions like an IMAP server. Organization belongs to the server, not the client software. Your folders are the same when you use Outlook from the office, Outlook on your notebook, or you use the web interface.
Exchange adds scheduling and integrates it with the email function.
You can record your appointments on your calendar or use Outlook to schedule meetings with other Exchange users. You can also delegate access to your mail or your calendar to your secretary.
