I have an Exchange 2013 server that run most smtp but now we have an application that monitor a pop3 account on the exchange every 2 minutes.
I enable the pop3 service but I'm getting a user name or password error out of the application so I try to setup as a pop aacount with Outlook 2013 and I'm getting the following error: Log onto incoming mail server (POP3): Your e-mail server rejected your user name. Verify your user name for this account in Account Settings. The server responded: -ERR Command is not valid in this state.
The user name on the server is support and the email is email@example.com
Under pop3 account on Outlook I enter the user name as firstname.lastname@example.org but still not work.
Password is OK because I can logon via OWA no problem.
