We have a Windows Small Business Server 2003 that we have been connecting to for years via Windows Mobile Devices. We now need to connect some users with iPhones, and have been having no luck. Apple wants $695 for any assistance in the matter. We have tried everything that we can find, but cannot find the answer. The closest we've gotten is to get the account all set up, the account gets verified without issue, and we go to the inbox on the phone, and don't get any errors. We also don't get any mail though, and mail sent doesn't ever seem to arrive anywhere.
The server is reachable on the web via OWA at https://mntts.com/exchange
(iPhone server setting used was mntts.com)
It is also reachable via https://acs.mntts.com/exchange
(iPhone server setting used was acs.mntts.com)
The local domain name is mattacs.local (iPhone domain used was mattacs)
The server's self-issued security certificate matches up to acs.mntts.com (the second server setting we tried). We have tried it with and without SSL, without any luck. We don't know if there is something special that needs established in the firewall, or on the server, or what, but if somebody could help, we'd like to have the step-by-step instructions on what we need to do to get this working. What is really mystifying us is how ActiveSync works flawlessly on multiple Windows Mobile devices for years, yet ActiveSync cannot seem to work at all via iPhones.
Thanks in advance,
