I have been struggling with syncing Blackberry calendar in a SBS 2003 environment. There would be a maximum of three BBs to sync to each users calendar. I tried installing BB Professional, but the instructions were geared more for full server instead of SBS, and I got frustrated. Reading some posts here, it would seem it's not best practices to do the install on the primary DC anyway. My main goal is to have the CALENDAR sync; the rest is not important. What are my options? Is the new Google Sync exchange-friendly? I would really like a simple solution to put this behind me.
