cheers for the replys guys.
Were using the free version of VMWare Server at the moment. Unfortunately we don't have a T-Support contract but I do believe that since we've recently bought a couple of new copies of BES we may be able to get some support.
I've checked mapi versions and they do match.
Oh and by FS i'd meant FileServer
Its a weird issue... pinging from the FS (on which the vm is sat) to Exchange is fine. Ping at the same time from the BES VM times out for a couple minutes at a time. Can't tell at the mo how often it happens but it loses the connection for quite a while then obviously has to rescan all the mailboxes when it comes back up, resulting in the mail arriving in batches.
One last question for now though. We brought the software through our UK phone supplier and were obviously given a UK SRP to connect to. Would it be best to contact RIM to see if its possible to switch to one nearer Sydney?
Cheers again
