In my case all I had to was to first setup active sync on mobile device (user name, password) and then in device there is an option for enabling or disabling the direct push. It depends on the handheld you are using and what operating system it is running on. In my case it was a TMOBILE mda. ________________________________ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Corey M.

I was told that to enable it I would need to map 443 from the Internet to my Exchange server, and also that I would need an SSL certificate installed. I'm wondering if anyone has done it with only 1 exchange server? I have 1 exchange server behind 1 firewall. No seperate exchange front end, no seperate smpt server, and we dont use owa, so no owa server. Just 1 exchange box. I always have concerns opening ports up, so curious what other people are doing. Would you only do this if you had a front end exchange box in a DMZ? Thanks in advance, Jon . I am no longer accepting emails at this email address.
