It is my understanding that there are only a handfull of users who keep a copy of their email on the server so you bet this is going to be a pain. I have pretty much told my "boss" that the the users who will be getting the BBs are basically going to have to change to Outlook if they want to sync wirelessly but I get the feeling that the point is not getting across. I could go on and on about how this network has been pieced together and it appears they want to continue down that same path.
One of the potential BB users actually has all of their internal email forwarded to an outside account and refuses to seperate the two. But this account maybe the easiest one to setup.
Anyway, Thanks for all of the help and for letting me vent a little bit.
