I have a customer that wants to enable active synch for his Windows Mobile Device. I have installed BES and Good Messaging before, but never the Exchange Native Active Sync. What are the steps needed to install? I want to know if this can be done over the air, or is there a client (pc) side install? I am seeing that many docs refer to the client side peice. Is there any dependancy on OMA to get Active Synch working or are they two seperate peices?
