I had to configure a gmail imap account for a friend on Outlook 2007.
Using settings from google’s page for Outlook configuration did not work for me.
I was getting “Error message-IMAP server closed connection Error Code: 0x800CCCDD”. I have tried almost anything, the connection to the imap server didn’t worked.

I have used thunderbird to test and it worked from the first attempt.

After a while I have noticed that the image with the account details has the password entered and the “Remember password” option checked.
So, I have filled the password field, checked to remember the password and , IT WORKEED.

Idiots!
