Hi,

We would like to run our own blackberry server BES 4.0 inhouse in conjuction with a remote hosted exchange service. This gives us maximum felxibilty for the BES without having to care about the Exchange.

We understand that MAPI communication will need bandwidth and latency < 35ms, on the other hand we're only 2-5 people, so I guess this might still be practical.

Would it be possible to run MAPI over HTTP/S or do we simply have to gurantee UDP connectivity on a certain port? The German exchange hosting company skyfillers has a service where they host the BES in conjuction with your internal exchange. Not quite our setup, but I guess they face a similar problem as we do.

Any ideas or experience with such a setup?

Regards,
Jakob

Bandwidth is an issue but if you are only 5 people it will probably be just fine. I have no experience with this but I imagine that you may not be able to configure the mapi over HTTPS for the BES to communicate to the Exchange environment. I would also guess that the remote Exchange hosting company might have an issue with you connecting your BES to their servers. Not trying to be a downer but I just imagine there will be some tall obstacles. Let us know if you get it going.
