I am having very simular problem, and haven't found the answer yet. I setup my old email server again behind the ISA server and it runs fine. I'm currently leaving it up, so the company has email. I'm a bit in over my head here, but if I do find a fix, I'll let you know. -----Original Message----- From: W.

I can get the Web Access to work, and I can even send mail, but I can't receive email. Has anyone dealt with this issue before.
