I feel like I'm dead in the water. We're switching phones from blackberries (which connect to our bez server, and I can't wait to dump that thing) to just using Active sync to connect to some new androids. To do this I installed a new Exchange 2010 server in our organization to eventually replace the old 2003 server. I've got two last problems to resolve (fingers crossed) to get this working. One being have active sync pass outside of our network. And two to have the 2003 server and 2010 share mail between them (which apparently isn't as easy as creating a connector between them). So let's look at them one at a time.
The problem seems to be this with activesync. I plugged in a wireless router to our network and was able to connect to active sync directly , but am not able to connect from the internet. So I figure this is because of the fact that active sync uses port 443. And port 443 is already used on our firewall (by the way we only have one public IP address. So I went into IIS on the new 2010 server and added a binding to Active sync for port 1443 (but did not remove 443). And then went onto the firewall and forwarded 1443 to the appropriate server. But activesync still won't work. Now tell me if I'm wrong in thinking how activesync is used. I believe that it uses IIS web service ports to communicate, and then IIS relays to exchange for the client, and exchange replies to IIS (not the client) and then it is IIS's job to communicate to the client. Am I wrong? If not, then why didn't this work?
Second thing is communication between our old exchange 2003 server and the new 2010 server. I thought you could just add a connector into exchange 2010 which would communicate back and forth for you, but the mailboxes which have been moved to the new server are not recieving anything from the outside. Now consider this though... We have a mail-wall. The firewall forwards all incoming mail to the mail-wall. If the Mail-wall accepts the message it is set to forward it to the old 2003 server. The mail-wall will not forward to muiltipule targets, so it has to forward to the 2003 server, and then I wanted it to be the job of the 2003 server to forward onto the 2010 server if the mailbox did not reside on the 2003 server. How can I do this??
I hope this was clear enough. I'm just typing really fast to try not to waste anytime I have left to solve this. If you need clarification. Please just ask.
Thanks a million.
