iPhone: Can Microst Exchange Server work without Data plan?

[mesamac]

I have iPhone 3G and recently I jailbreaked it. I got AT&T service just voice only. No data plane and I asked them to block all internet WAP access.

I have WiFi at home and our company has Microsoft Exchange Server for push server. When I configure, it is not able to connect to server.

Just wanted to confirm, can I access corporate Microsoft exchange server only via AT&T data service?

I know my co-workers with same server configuration (without) any VPN, they can connect to this server.

Any suggestions?

Thanks.

It should work fine, as long as:

1) Exchange mobile access is enabled for your active directory user account (check with your IT deptatment if you're not sure)
2) You have the mail certificate for the exchange server installed
3) Your IT department has configured their firewalls so that the Exchange server is accessible from the Internet

How can I make sure I have mail certificate installed?

Thanks.

Like the above said, you can access Exchange servers through WiFi. But your IT department are the gods, they can do basically anything with the server.

For certificates and all that stuff, that's their turf.
