I have an Exchange 2003 SP2 backend server, we currently use it for just internal mail, it has OWA enable but only for local LAN users. We have no front end servers.
We have just got hold of a load of HTC Desire smartphones and want to enable push email for them.
Do I need a front end server? one article I have read says direct push is enabled by default out of the box.
How do I publish my exchange server to the internet so that the devices can see it? is it just a case of opening up port 80 and 443 for that server on the firewall?
also, if I do need a front end server, do I need 2 licences of exch 2003? I am running exch 2003 standard edition.
many thanks for any help you can give
