Hi there,

I have a client who is having constant problems with his outlook 2003 on his windows 7 laptop. We can’t seem to find anyone who can help solve this problem. We’ve gone through all the tests that the Microsoft website has suggested to no avail. We’re hoping that someone out there has had a similar problem to ours.

Our client can’t seem to send emails. He can receive emails most of the time. He has this problem when he’s at home and when he travels as well. There doesn’t seem to be a pattern to his problem. We have done several tests changing the kind of ports and preformed these tests on a PC and a Mac. We’ve tried:

1) Use out going SMTP port 587
2) Change the Outgoing server authentication method
3) Use IP address as out going mail server

I made sure Authentication was checked changed the port 587 and 110. I received the error: Trying to log into the SMTP server "smtp.example.org" failed. I made sure the user name and password I entered was correct. During one test when I took the account back online, the emails downloaded just fine. I then went to the PC and to outlook to try to get the email account set up there and it wouldn't work.

I set everything up with the authentication and port change and received this error:

Task 'mail.example.org - Receiving' reported error (0x800ccc90): Your incoming (POP 3) e-mail server has reported an internal error. If you continue to recieve this message, contact your administrator or internet provider (ISP). The server responded 220ps11.myhostcenter.com ESMTP

MAC pushed it through, but the PC could not. Is there a compatibility issue with the emails clients and the server? OR is there a setting some place else I should be checking?

Here are the results of several of the other tests:

(Please NOTE: The “Authenticate” button was checked throughout all of these tests.)

Eventually…after a couple of hours:
