Working with the BDM has not been a general pleasure for me and other technicians where I work. It doesn't sync all the time, most likely due to corrupt organizer data and/or buggy software. The weird thing is that it was working kind alright when we had an Exchange server, but it got crappy when we migrated to a MAPI connector with Sun. I got it syncing by installing the exchange redirector BDM (we're still using outlook) and disabling redirection?! In the process of stumbling on this, I became familiar with just about every troubleshooting BB trick. Fun!
