I have a customer who currently has an SBS 2008 server with all users and mailboxes. They are looking to move away from the internal exchange server and use a hosted exchange setup. I haven't seen any good documentation on how to accomplish this. I can move MX records but I'm guessing the SBS exchange server will confilict with the Hosted exchange server when the clients attempt to connect with Outlook. What should I look out for? Will updates to the server cause problems down the road?
