It was set to allow Anonymous Authentication (this is required by the Exchange server) and Windows Authentication. Then we checked the authentication allowed for EWS in IIS. When we tried to browse via a browser on the Mac, it wouldn’t prompt for any credentials, just show a blank page, where a Windows computer would actually show something useful.
Outlook 2011 doesn’t use MAPI, it relies solely on EWS (Exchange Web Services). The solution? Keep reading! The solution When we finally found the solution, it was a fairly basic one. Anyways, we struggled a long time as we kept getting no feedback on the process from the Mac. Let me be honest and say that at my company, we’re not exactly good when it comes to Macs, we’re actually quite horrible. It would just sit at an empty mailbox, no connection errors, no authentication errors, nothing. When he put in the information for the Exchange server, nothing happened. This customer also has a few Macs running Office 2011, where Outlook unfortunately refused to do anything (literally).
Everything was set up like it should be, Outlook 2007 and Outlook 2010 clients worked like a charm. A colleague of mine was setting up a customer for Exchange 2010.
