POP3 authentication using email address in Exchange

  • 772

I'm running an Exchange 2010 server. I need to allow POP3 authentication using an email address as the user ID instead of the domain username. Here's an example:

AD Domain: domain.local
Email domain: domain.com
Username: johndoe
email address: [email protected]

John logs into his computer using the username [email protected] but has an email address that is [email protected]. Can I enable POP3 authentication using the email address rather than the UPN? How do I do this?

exchange exchange-2010 pop3

    Well, looks like the answer is that there is no answer. There is no way to do this. Exchange will only authenticate using domain username.
