This guide will demonstrate how to configure Mac Mail using Exchange on Mac OS 10.6 (Snow Leopard) or newer. Mac Mail provides a robust experience with the Microsoft Exchange environment. This will enable access to e-mail, calendar, and more features on your desktop. Calendar is available in the separate "Calendar" app (formerly known as iCal).
Open Mac Mail from the Applications folder on your Mac OS X computer.
If you have never set up your Mac Mail, you may see the "Choose a Mail Account to Add" pop-up.
If you have used Mac Mail before, you can add a new Account by going to Mail and then Preferences.
Then click the plus button at the bottom to create a new account.
Select "Exchange" from the list given.
Fill in your name, email address (firstname.lastname@example.org), and MyID password.
You may see a certificate warning. Choose Continue.
If Mail crashes during this process, repeat steps 1-3, then disconnect from the internet. If you are on wireless, disconnect from Wifi. If Ethernet, disable the connection or unplug the cord.
Verify that both check boxes are checked to synchronize your Address Book and Calendar using Mac Address Book and iCal. Click Create.
You should now see your Inbox under Mailboxes on the left, and your e-mail folder will be listed below that. You will have to use the arrow to expand your folders.
