I'm experiencing the same problem Outlook 2007 error is: 0x800CCC0E
I've tested this on Vista, all clients (Outlook 2003, Outlook Express, the
new Windows Mail in Vista) work OK, but only in Outlook 2007 the error is
generated.

It only has a problem receiving mail, sending is OK that's why the test
message
is generated.

I cannot imagine is is a problem at the mail provider, since all other
clients work without problems.

So I'm also trying to find a solution for this (other than not using IMAP..)

Hi,

I have an IMAP account which is working on Outlook 2003 with no problems.
When i enter all the data in Outlook 2007 it won't even connect to the server.

Test mail.

When i do a test connection it always sais failed.

Can someone please help me? Thanks
