i have a client that is using bes with groupwise. he is moving to google mail. he wants to make this switch on the bes and not have to re activate on the devices. he has close to 16,000 users. is there a way to do this?

Moved to BES Admin corner.

I don't see a BES for Google Mail anywhere on RIM's website...

Enhanced Gmail plug in maybe?

This sounds like a very strange plan.

But yes, this should work. If googlemail needs you to assingn new outgoing email adresses to all users, and, if you can batch assign your 16K users new email adresses in groupwise like with a recepient rule in exchange, you dont have to reactivate your BBs.
(I dont have much knowledge about groupwise, and never tried googles offer for organizations)
