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.

macOS 13.4 fix found!

We've had this problem for multiple client devices since macOS Monterey. Back then we had a fix that worked however since macOS Ventura, no fixes have worked.

Since updating to macOS 13.4 the following fix works:

Close Outlook, Mail and Calendar apps
Open Activity Monitor
Force quit the process called "exchangesyncd"
Relaunch the Calendar app and give it a few minutes

This issue has caused us a lot of nightmares so hopefully this works for you all.
