OS X Mail: Using Microsoft Exchange (EWS) accounts

Learn about using Exchange (EWS) accounts in Mail with OS X v10.6 or later.

Before you begin

Note the following items when setting up your Exchange account in Mail.

  • OS X Snow Leopard and later support Exchange Web Services (EWS) as a connection to your Exchange server. If your Exchange server does not use EWS, check with your Exchange administrator to see if an IMAP connection to the server is available instead.
  • Your Exchange server must use Exchange Server 2007 or later. If you are using Exchange Server 2007, you must have Service Pack 1 with Update Rollup 4 or later installed.  
  • For best results, use Software Update to make sure OS X is up to date before setting up your Exchange account in Mail.
  • You can add as many Exchange (EWS) accounts in Mail as you would like.

Adding an Exchange (EWS) account to Mail

Exchange accounts can be added from Mail preferences.

  1. Open Mail (click its icon in the Dock, or open it from the Applications folder).
  2. From the Mail menu, choose Preferences.
  3. Click Accounts in the toolbar.
  4. Click the Add Account (+) button. 
  5. Select Exchange from the list of account types available.
  6. Enter your name, email address, and password in the sheet that appears, then click Continue.
  7. If Autodiscovery is not enabled on your Exchange server, an additional configuration sheet appears. Enter your server address on this screen. If you aren't sure of your server address, contact your Exchange administrator.
  8. Features such as contacts and calendars can also be used with Exchange. Select the options you want to use with your Exchange server, then click Continue. 
  9. In earlier versions of OS X, a summary sheet appears when you complete setup. If this information in the summary appears correct, click Create. If you need to make changes, click Go Back. Select the option "Take account online" to start using your Exchange account immediately after finishing setup.

If large Exchange mailboxes don't download new content

This may happen if certificate authentication is enabled on the server and your mailboxes have a large number of email messages. Microsoft recommends that you keep fewer than 5000 mail messages in Exchange mailboxes. You may see this issue with mailboxes that have more than 11000 mail messages.;

If you cannot send messages via your Exchange account in Mail with SSL enabled

The SSL port setting for your Exchange account may be incorrect. Check with your Exchange administrator for the correct SSL port setting, then change to the appropriate port number in Mail preferences if necessary.
