Well, first the good news. The newest version of GCalSync is working without crashing my Outlook. It takes forever and a day for a sync cycle to complete, but it works.
So now I have a separate “Pointy-Haired Dave” calendar next to my other GCals that I can toggle on and off to see some work activity conflicts when looking at my home calendars.
Except … it’s still not picking up (this is a known and long-term problem) some (a few) meetings where I am an invitee don’t sync. Things I create are fine; things I don’t … sometimes aren’t. This (and the support) have gotten better since earlier versions, but it’s still a bit annoying.
On the other hand, the whole thing is pretty keen, so if it’s working at 95%, I’m not going to complain too bitterly.
