When Gmail doesn’t work in Outlook behind a firewall

If you have Gmail setup in Outlook on a computer and you are not able to send any mail, it may be a problem with the way the firewall is handling traffic. If you don’t have access to the firewall, here is a method that may help.

Go to the server settings for the Gmail account in Outlook and set the SMTP server port to 587. Also, set the encryption to Auto.

That’s it!
