Mac Mail unable to connect to Exchange 2010, Entourage EWS is fine

A little stumped here:  We have a single Exchange 2010 server, UC certificate from Godaddy, and when we try to connect Snow Leopard Mail to a mailbox we constantly get prompted for username and password.  However Entourage 2008 EWS edition on the same machine connects to the mailbox no problem.

We ran the EWS test at http://testexchangeconnectivity.com against the Exchange mailbox and it passed.  

The only error we see is when first adding the account, Mail throws the warning that 'the server at autodiscover.mydomain.com rejected the username and password.  We have a public A record pointing autodiscover to our Exchange server.

In IIS - Autodiscover Authentication is set to enable Anonymous, Basic and Windows;  SSL is set to require SSL and Ignore client certificates.

Any help greatly appreciated.  Thanks in advance

Does it connect when you put the credentials in? Maybe it could have the wrong credentials in a key chain and when it tried to log in with the information on that key chain it prompts you for the right information.

Look in the Key Chain program, located in the utilities folder, and delete the key chain that has the mail credentials. Then restart the mail program, when it asks for the credentials, put them in, save to key chain.

Another thing could be you need to add the domain before the user name like domainName\Username.

I would try them both.
