I administer a CommuniGatePro 3.5.9 server and access my mail via IMAP with Entourage Version 10.1.1 (2418). Things are generally good except periodically at no regular interval that I can determine, Entourage throws up the following error:
Error
Mail could not be received at this time.Explanation
Invalid account ID or password. Check your account settings.
Of course nothing has changed on either the server or in my account settings. The next connection to the server completes without error. If I check the server logs, this is the relevant information logged:

This IMAP service requires a secure connection (SSL) = unchecked
Override default IMAP port: 143 = unchecked
Always use secure password = unchecked
It appears that when Entourage accesses a server advertising NTLM capability it defaults to trying that method first and if it doesn’t succeed drops back to clear-text authentication. But why is it generating an error sometimes? Either ignore the failure and drop back to clear-text or generate an error consistently every time, right?
Can anyone provide any insight into the matter?
