International support for blackberry

Our company uses centralised Exchange ( and blackberry )servers in the US and the UK and we have offices scattered around the globe. Our network infrastructure connects all the global offices to our headquarters in the US where our internet connection also resides.

Is it possible to make use of the blackberry servers in the US to run a blackberry in other countries ( which do have networks that support them ) ? In this instance a message is coming through saying "the result of the last transaction was 'message expired at network'

With the latency between our mail servers in the US and the blackberry in Australia is it possible to configure this to work?

Many thanks for any help you can offer

We have had considerable success in using T-Mobile's service in the UK and Europe (as well as the normal coverage here in the States.  Our BES and Exchange servers are in the same office in Seattle.

I think the key here is the relationship between your mail servers and the BES (at least the BES and the particular mail server that holds the mailboxes of that group of blackberry users).......ideally they should be on the same Lan......you don't want them trying to talk to each other over a VPN that is dependant on Internet speeds.  Beyond that, if the servers can talk to each other effectively, the BES should be able to talk to any hand-held service provisioner in any country where they have service.  

That's the Catch 22..........finding a service provider that allows your handheld users to receive/send in all the different locations they work from.

After going through the scenario withthe telco provider down here we have found a workable solution.

We can run the blackberry units in Australia from the BES and exchange servers in the US aslong as we stay on the  Telstra gprs network locally. Attemps over other gprs networks were unsuccessful even after assurances from their tech teams that the network should support it.

Some latency issues have arisen but these are being looked into presently.

Thanks again
