Does anyone know the official release date of Exchange 2003? I had heard summer of 2003, but I'm not sure if that is accurate. I have a customer that is looking to purchase Exchange 2000 soon but if 2003 is near I may tell him to wait and purchase the license for 2003 so he can install either version. This way he can use 2000 for now and then we can install 2003 after SP1 is released.
