Mac Calendar not syncing with Exchange on Ventura

Just upgraded to Ventura. When I enter a calendar event in Mac Outlook is does NOT show up on my Mac calendar, but it does show up on my iPhone calendar immediately. Also, if I enter a calendar event on my Mac calendar and designate my Exchange calendar to put the event on, it does NOT show up on either my iPhone calendar OR the Outlook calendar on my Mac. I used to periodically get this happening on Monterey after a few days, but it fixes itself on a restart -- however, that is not case now, a restart of the Mac does not fix the problem.

Mac Mail seems to be syncing just fine -- no issues with that, so there is something going on between the Mac apps and the Exchange server.

I fixed this Problem with a work-around. On Ventura 13.1, I completely eliminated the Exchange account (System Settings --> Internet Accounts --> "Exchange" --> Delete Account), rebooted, then added it back in. Everything seems to be syncing fine for 3 days now. This work-around has shown up in other threads as well.

You have to go through the entire deletion of the account and re-add -- make sure you don't just stop syncing the calendar using the toggle on/off button.
