I have a SBS 2008 setup as: Mycompany.local domain and receive mail for company1.com in exchange. I added in the “Hub Transport” > “Accepted Domain” company2.com” I have a domain user JohnM who connects with outlook to his exchange account. I added to his Email address properties to receive JohnM@company2.com in SMTP. I am looking for a way to have John to be able to send email as JohnM@company2.com and JohnM@company1.com from Outlook. That’s when I tried to add a second mail account to his Outlook profile to connect to JohnM@company2.com with POP3. Maybe there is a better way to do this? With JohnM@company2.com I am getting: Log onto incoming mail server (POP3): Your e-mail server rejected your login. Verify your user name and password in your account properties. Under Tools, click E-mail accounts. The server responded: -ERR Command is not valid in this state. Please advice.

First try to configure ur company2.com mail in other pc or like window live by POP3.If y can able to send and receive then there is something u have to do in ur outlook.Else ur have to do some thing on johnM@company2.com account. -bpara

Hi, Please check the Authentication on the POP3 Connector. You should select Plain text login (Basic authentication), then restart Microsoft POP3 service. Thanks Allen
