Anyone had any experience running BES (4.1.4) against Exchange 2K3 and 2K7 at the same time? We are looking at introducing an exchange 2K7 box into our exisiting 2003 environment and moving a subset of our users onto the new box. I am a little worried about the bes having to talk to two different email databases with two different mapi32 and cdo dll versions.

Initially you will have some calendar issues as the 2007 MAPI/CDO does not work that grear with 2003. No biggie, just remember to set permissions using the Exchange 2007 power shell. Just search the BlackBerry Technical Solution Center for exchange 2007, lots of good info there for ya.
