Outlook 2007 0x800ccc80 error code


New Email
My MS Outlook stopped working about 3 days ago. 2 days ago, I received a burst of over 100 email messages, but none of the messages in the Outbox were sent. Outlook went dark again, intermittently receiving emails, but not sending.

The initial error code was "Unknown Error 0x80040600". I changed the Outgoing server Port number to 587.

Now I receive the 0x800ccc80 error code.

I am using MS Outlook 2007 with POP3 / SMTP. My internet provider is MSN.

Any advice would be appreciated.
