Our company uses an Exchange 2003 server hosted by a sister company of ours and their IT staff. They setup a Blackberry Enterprise Server a few years back and we have several users (myself included) which use it. However, we have the need now to be able to use non-Blackberry devices (iPhones, Droids, etc.) with the Exchange server, however the sister company is being very very slow about adopting this. The sister company provides employees with Blackberries where we don't, so that might be the problem :).
Anyway, we're trying to investigate a way to enable non-blackberry access to the Exchange server. I know normally this is trivial, however in our case we have no rights or access to the Exchange server at all. I've come up with two options by myself:
1) Outlook Web Access: Route the users via their iPhone to a secure page, allow them to login with their AD credentials and then send them to OWA. This is maybe the simplest, however it doesn't do "push" notifications, such as new e-mail.
2) Some type of middleware. Something to sit between Exchange and our mobile devices to act as a intermediary.
We also need the ability to be able to "wipe" the device, such as it being lost or termination.
Just looking for some advice.
