A customer uses Entourage for Mac to retrieve mail from the MS Exchange server. Entourage for Mac fails to connect to MS Exchange 2010 with this error message:
Cannot connect to Exchange server

Entourage for Mac allows you to collect mail from MS Exchange 2010 using POP3 or IMAP protocols. However, operations with the Calendar fail with the same error message.


Entourage 2008 and older versions use WebDAV for retrieving messages. WebDAV is no longer supported in MS Exchange 2010.


There are two possible solutions.

1. Microsoft released a special version of Entourage 2008 for Mac called Web Services Edition. This version uses Exchange Web Services to communicate with the Exchange Server. Use the following link to download this version and find upgrade instructions.

Microsoft Entourage 2008 for Mac, Web Services Edition

2.  Use Outlook for Mac 2011 or an integrated Mail client with Mac OS X Lion instead of Entourage. This software supports Exchange 2010.
