Any other information
this may or may not be related, but previously I was getting some weird error messages on certain events that there was "extended private data" on certain Google events (birthdays). I have not done anything fancy with respect to birthdays. So, in order to make this error go away, I unclicked the "Birthday" calendar type in Google to make all the birthdays go away.

I have gotten OGCS to work now, by doing a series of one-way syncs to delete items in each calendar that originated on the other side, and then doing a bidirectional sync. So my urgent issue is over, but whatever happened may be of concern to you.

The issue looks to be to a possibly spurious m appointment with 6570 exceptions to the recurring series - so it was trying to iterate them all. I've no idea what causes all these exceptions, but I have seen it a handful of times before.

2024-12-10 12:03:41,751 DEBUG 12 OutlookGoogleCalendarSync.Outlook.Calendar [440] -  7/1/2021 10:00 AM (R) => "m"
2024-12-10 12:03:41,753 DEBUG 12 OutlookGoogleCalendarSync.Recurrence [411] -  This is a recurring Google event with 6570 exceptions in the sync date range.

If that item was on your Birthday calendar, then excluding that whole calendar will have worked around the issue. Equally, you could delete that m series and then bring that calendar back in scope.
