Hello all,
I am currently preparing to deploy a production forefront TMG. My organization uses google apps as an email platform, and we use outlook as a mail client. We configure outlook to pull emails down via pop3. This works with our current ISA server, but for some reason when i switch client computers to use the TMG outlook cannot connect gmails pop3 server. I set up a rule in TMG to allow pop3,pop3s,imap,imaps,smtp, and smtps through. What am i missing?
