Apple Mail for OS 10.7 - OS 10.8 and OIT's Exchange service go hand in hand.
These are instructions for people who are already using Apple Mail for OS 10.7 - OS 10.8, and want to configure their program to access an Exchange account.
If you cannot connect to Exchange and you have SecureMac (OIT provided application package that contains Fetch and terminal shortcuts) installed on your computer, you need to delete a file on your computer. Click here to find out how.
Exchange is now setup, and you will be able to see mail, calendar events and folders you have in your Exchange account.
