Why is my mailbox password being rejected?

If your mailbox password is rejected you may see an error message similar to the following:
There was a problem logging onto your mail server. Your Password was rejected. Account: '', Server: ', Protocol: POP3, Server Response: '-ERR invalid user or password', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC92

First check your mail client (Outlook or Outlook Express) settings, making sure that the POP3 and SMTP servers are correct, as well as user name and password.


Testing your connection using the Telnet command


Step 1
Click the Start button then RUN type in cmd on (Windows NT/2000/XP) or Command (Windows 95/98/ME). This will open a new command prompt window, with white text on a black screen.


Step 2
Type in the following replacing with your actual domain name. telnet 110 then hit the Enter key on your keyboard.


You will then be connected to the email server.


During this process you may receive a message from your firewall or antivirus software. If this happens you should check your firewall and antivirus configurations as this is likely to be why you are unable to connect.


Step 3
Type in USER followed by your email address e.g. USER and then click the Enter key. You will then get a message +OK Helo there. +OK Password required.


Step 4
Type in PASS followed by your password e.g. PASS j0eb105 and hit the Enter key. If it is correct, you will get an OK logged in. message.

If you can do this, you have connected to the mail server and the problem lies somewhere with your email client.
