Apple Mail for OS 10.6 and OIT's Exchange service go hand in hand.
To make sure your iCal is configured properly for Exchange follow the steps below.
Starting February 2015, campus units and departments began being migrated to Exchange Online, on an individual basis. If your department has been migrated, please visit the Exchange Online service area for more information.
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.
