I have Exchange 2003 server which is part of a multisite network.  Iphones
can verify with the serverwhen setting up the account but I get an error in
the event log when they try sync with exchange.  There are 3 exchange server
in the network.

All service packs have been applied.
The error is: HTTP status code: [501]. Verify that the Exchange mailbox
Server is working correctly.

I posted this under connectivity but I did not get any answers.

Your help would be greatly appreciated.

Regards
