I have just set up a new Exchange Server 2007 on Windows Server 2008 and Email is working great. My Client wants to sync his calendar and contacts on his blackberry curve but he can only get his email there at this time. He has already made a considerable investment in all the hardware and software and hate to tell him that he has to spend another $3000.00 or more on BES. Is there a good cost effective solution to enable him to receive his contacts, calendar, and email to his blackberry curve when he is on the go? OWA is already enabled and working great.
