Allow 1 way syncing of read-only google calendars

[BrettMichlitsch]

My kids sports teams, church calendars, and my sports leagues all have google calendars that are read-only calendars. It would be great to be able to sync those to my outlook. Just one-way from google to outlook.

That should just work...! What happens when you try?

I cant create a profile without an exception occurring. I was just pressing continue through the exception then saving the profile. Everytime I load the profile I get this exception: I'm guessing maybe that why this isn't working.

If I press sync for that profile I get this exception from the log files:

Yes, that first error at least will be fixed on #1480 - let me know if it works after applying that hotfix.
