Ok question which Im sure is easy to answer...

I am about to move our Exchange 2010 server to a virtual server at a data centre and all users are going to connect using RPC over HTTP no problem there.

BUT we also have a BES server running version 4 for Exchange can this still work? can I move it or leave it where it is?

All advice would be great.

Cheer in advance people.

    Hi Steve,

    BES v4 in any of its incarnations is not supported for Exchange 2010. The recommended version of BES is 5.0.3.

    I would recommend keeping the BES on the same LAN as the Exchange server rather than running it from a remote location. Although it is technically possible, it will give sluggish response times and an increase in WAN traffic.

    You can see the BES compatibility matrix here:

    Please refer to the compatibility matrix below:

    BES 4 is not supported nor recommended on Exchange 2010. Virtualising BES 4 is also dependant on the Virtualisation and version.

    Why not deply BES 5.0.2/5.0.3 and use Enterprise Transporter to migrate the users?

    BES is very sensitive to latency and bandwidth due to the nature of MAPI. As a result, co-location of the BES and Exchange Server is the supported and recommended approach (MAPI has issues if latency exceeds 35 ms).

    With regards to BlackBerry, also consider the SQL version if/when you upgrade.
