I get an error message in Outlook 2003 when setting up a mailbox user from Exchange 2007. I have the POP3 service running and I have tried to logon using "user", alias username. "domain\user", "domain\alias","domain\user\alias" and still get the same error.
What is the proper Outlook settings for Exchange POP?
The only reason I am using POP is to set up a mixed user in outlook. I need one exchange account and an additional POP email account with a different domain that I can choose a which "from" address to use within a single inbox of outlook.
