Configure Apple Mail for Exchange Web Services

Exchange Web Services (EWS) is a newer data synchronization protocol that seamlessly syncs SmarterMail messages, contacts and calendars with Apple Mail, iCal and Address Book. NOTE: Before you can configure a mailbox to sync using the Exchange Web Services technology, you must activate the Exchange Web Services add-on.

Applies to All Versions of SmarterMail

Follow these steps to set up Apple Mail to sync with SmarterMail via Exchange Web Services :

  1. On your Mac, open System Preferences.
  2. Click Internet accounts.
  3. Click Exchange.
  4. Complete the display name, full email address and password fields.
  5. Click Next.
  6. Type the internal and external URL to your SmarterMail webmail. Your internal and external URLs should be the same and follow this format: 
  7. Click Next.
  8. An account summary screen will display. Click Continue.
  9. Click Add Account.

Apple Mail is now configured to sync with SmarterMail. Depending on how much data there is to synchronize, the first sync may take a few minutes.

NOTE: For mailboxes that will process and store large volumes of email, it is recommended that they be set up to connect to SmarterMail using IMAP as EWS performance suffers when processing large volumes of email.

I think EWS expects or requires https, not http. This should be clarified in item 6.
