Email problem

[steq184]

I am running xp pro and outlook 2003.
I have entered in all my account details etc into outlook and when I click on Test Account Settings ALL task complete without a problem.
BUT when I click on Send/receive I ALWAYS get asked to enter my password in again........I do this and click Save this password in your password list BUT the send/receive fails and I get this error message:
Receiving reported error (0x800CCC92) your email server rejected your login. Verify your username and password in your account properties.

I have entered the correct username and password and have confirmed with VM that these are correct. They say they can help me fix this problem for £5 but as I pay over £100 a month to the money grabbing ***** I politely declined their help!!!

Any ideas??

For the past couple of days I sporadically get "Error from server: -ERR Protocol error.. Did you change your password?
"

I changed my password a few days ago......even more baffling is that although I have entered my password into the outlook settings every noiw and then when i check back the password has disapeared????
