With Snow Leopard, the Mac has a built-in support for the latest version of Microsoft Exchange Server. This article will guide you through Mail.app setup to work with your Exchange 2007 or Exchange 2010 mailbox. Please note, MacMail on Snow Leopard OS doesn't support Exchange 2003 mailboxes.

MacMail Setup:

1. Starting from the Mac Desktop, clink on the Macintosh HD Icon.
2. Select the Mail.app
3. Click on the Mail button at the top of the screen and got to Preferences.
   
   
4. On the Preferences page select Accounts at the top of the page. 
5. On the Accounts page click the “+” in the bottom left of the window. It will open Add Account window.

   • Full Name:  Users name as you want it displayed on emails.
   • Email address: Primary email address of the user.
   • Password: Mailbox password
     Please Note: At this point if there is an Autodiscover record for the domain of the email address being set up skip toAccount Summary #2.  If not then continue on below for instructions on connecting to the server manually.  
     If you would like to set up an Autodiscover record for your domain please see the Autodiscover KB article.

 Exchange account access:

Unlike Entourage or Outlook Use of the MacMail connection to our Exchange servers requires the use of three separate applications to handle Email, Contacts and Calendar.  The three programs are the following.

• Email: MacMail
• Contacts: Address Book contacts
• Calendar: iCal
