When you try to send or to receive e-mail messages in Microsoft Entourage 2004 for Mac, you may receive an error message that is similar to one of the following:
Error message 1
Error message 2
Authentication failed because Entourage doesn't support any of the available authentication methods.
Mail could not be received at this time. The server for account "xxxxx" returned the error "command not implemented." Your username/password or security settings may be incorrect. Would you like to try re-entering your password?
This problem occurs when the Post Office Protocol version 3 (POP3) server or the Simple Mail Transfer Protocol (SMTP) server uses NTLM version 1 authentication. Entourage 2004 for Mac no longer supports NTLM version 1 authentication.
Note Earlier versions of MSN, The Microsoft Network, POP3 servers or SMTP servers may still use NTLM version 1 authentication.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
