Can't connect to exchange 2007 across IPSec

I have several sites on different IP ranges connected via IPCOP's VPN (IPSEC) connections.

I recently upgraded from exchange 2003 to 2007 since the upgrade my users on the remote networks can't connect to exchange unless they PPTP the main network.

I can ping across the vpn networks, and users authenticate back to the AD Box it is just exchange that won't connect.

Any suggestions

Are the clients in the same AD site or diferent?
Is all the mail central in one location?

Hey,

Clients are normal Exchange 2007 (SMTP)
Clients are in same AD
Mail is Central
Latency not a problem it worked before Exchange 2007 upgrade
OWA works fine.

Seem that Exchange 2007 client and Exchange 2007 Server don't want to communicate over IPSEC.

Could someone else give me some advice here.

To explain, I have multi office hooked up via ipsec.

Users with Outlook 2003 can connect to exchange server, but users with Outlook 2007 can't over our office to office IPSec link.

If the 2007 users connect via pptp it works.

Weird.

Any ideas?
