I have 2 shared Google calendar that I have added to my Outlook calendar using the Google "secret address in ical format". When new things get added, I can see them in Outlook, but if an event is changed (description for instance or time), the changes don't sync to the Outlook calendar. The same thing happens with deleted events; they aren't removed from my Outlook calendar. Some of the changes were made more than a month ago and still have not synced, but new entries have synced. I have tried deleting and re-connecting the calendar. I've attached an example of the changes not shown for one of the calendars.
I just got a new computer with Windows 11. I was having this same problem on the previous computer using Windows 10.

I've never heard of the cleansharing thing, so I'll give that a try. It just seems so ridiculous that Microsoft doesn't fix this problem so that we don't have to keep redoing the darn calendar.
I have this problem constantly and the only thing that sorta helps is to set a recurring calendar reminder to reset my secret address (and also delete and resubscribe within Outlook) every 2 weeks or so.
Another thing that sometimes maybe helps is running the Outlook desktop app with the command line argument "-cleansharing" every so often. You can do that by pressing Windows key + R, then type "outlook /cleansharing".
I've had the same problem, again, just today in May of 2024, so no, the problem is not fixed.
Here is something you might try. Remove the shared calendar. Then go into the outlook web app and re-add the shared calendar and then see if it syncs?
Try right clicking on your shared calendar in the Outlook app and go to the synchronization tab. What does it say in the statistics folder?
