reported error (0x800CCC90)

[GHI]

I have recently started to receive the following error messages:

reported error (0x800CCC90) : 'Your incoming (POP3) e-mail server has
reported an internal error. If you continue to receive this message, contact
your server administrator or Internet service provider (ISP). The server
responded: '

reported error (0x800CCC91) : 'Your e-mail server rejected your user name.
Verify your user name in your account properties. Under Tools, click E-mail
accounts. The server responded: -ERR syntax error : USER username@domainname
'

When I go into my account settings and test I receive the following
response: reported error (0x800CCC91) : 'Your e-mail server rejected your
user name. Verify your user name in your account properties. Under Tools,
click E-mail accounts. The server responded: -ERR syntax error : USER
username@domainname '

I have read and followed to other post on this matter (i.e. going into the
Advance Option and clicking 'Enable logging (troubleshooting)') but without
success.

Please help.

There are not Outlook problems. Your mail servers are having problems and
you'll need to contact your mail provider.
