I have searched and read the full post and not sure were to go,

We have an current exchange 2003 server, current windows 2003 with BES installed (4.1.4.15), and we just added an exchange 2007 server (sp1). My device was working great on the 2003 exchange and BES, but last night as part of our testing we moved my mailbox to the new exchange 2007 server. (the bes server still has the exchange 2003 ESM on it). The BES mailbox is still on exchange 2003.

Now my device will not sync, will not activate wirelessly, it won't do anything. We have removed me from the BES, whiped the device and still will not activate wirelessly.

On the BES console I see my mailbox, and it lists the server as the new 2007 Exchange server.

I am going to try to ativate it with the cable and see if that makes a difference.

I thought I had the permissions set right on the Exchange 2007 server but I will try to check them as well.

When trying to wirelessly activate the device I get an error stating the server was not responding.

Any thoughts or help would be great, we have a small group that use BES, so if someone says, "just update the CDO/MAPI on the BES server and migrate your other users to 2007 and all will work" i might be able to try that.

Thanks
Dan
