Okay, I thought I had everything straightened out, but it just seems that the combination of Outlook and the way I’m generating my “birthdays” calendar on the Mac is not happy. It seems like things go wrong on the MobileMe site after going from iCal, to MobileMe, to Outlook, and back to MobileMe. It’s that last part, after Outlook does whatever it does to the calendars and pushes it back to the web, where everything goes wonky. If there was a way to just push the calendar to Outlook, and not let Outlook push it back to MobileMe, then I’d be OK. I wouldn’t mind treating the calendar as read-only in Outlook. Oh well, I guess I’m going to have to de-sync the calendar on my PC for now. I’ll leave the contact sync going, since that seems to work fine.
