I have set up an Exchange mailbox in Outlook 2000, but I am missing some folders. I can only see the Deleted Items, Inbox, Outbox, and Sent Items folders. The one I really need is the Calendar folder. Why can't I see those other folders?
I'm betting that the problem here is that you haven't set the Exchange mailbox to be your default delivery location. If you do that it will create those folders for you.
In Outlook go to Tools > Services. On the Delivery tab set the default delivery location to be the Exchange mailbox. You'll probably have to close and restart Outlook at this point. When it starts, you'll get a message indicating that the default delivery location has changed and asking if you want to rebuild the Outlook bar. Click Yes and you should be all set.
