I have a friend who wants to get a Blackberry to sync his Outlook calender. He uses Outlook stand-alone, without Exchange. Is this possible?

I manage a small BES server on my network where we run Exchange 2003, but don't have any experience with the desktop redirector or with Outlook w/o Exchange. But from what I've read, you need Exchange to use the desktop redirector.

If it won't with the desktop redirector, is there any solution at all for an individual to sync his desktop calendar with the Blackberry?

Thanks,
