Gmail via Outlook - unable to send

[MSPilot]

After following all the instructions for configuring both the Outlook and my Gmail account, according to http://mail.google.com/support/bin/answer....&topic=1555 I still get an error when pressing "Test Account Settings..." : the first 4 checks succeed, but the 5th - "Send test email message" - gives the following error message: "Unable to send test email Message. Please verify the E-mail Address field."

In this situation, I receive Gmail email via Outlook, but cannot send (the email I compose and send, remains in the outbox).

I tried changing the SMTP port to some 587 (instead of 465), like was advised here in another thread, but to no avail.

Anyone have any idea what is the problem?

Thanks a lot...
