Exchange/ Outlook calendar entries not syncing with ical
I had this same issue when I upgraded to Ventura. I found there is a process called exchangesyncd that controls the sync with the calendar app (and probably other things like contacts, notes, etc). The point is that I was able to go into Activity Monitor (use CMD + Space and type activity monitor in the search bar), and then type exchangesyncd in the search field within Activity Monitor, do a force quit on it (select the process on the list and then hit the X shaped button on top then force quit). It will take several seconds for the process to restart by itself, and then a few more seconds for the sync to start working on the calendar app. It took maybe 20 seconds in my case to start seeing the calendar sync again.
I remember back in Monterey I had this issue pop up every now and then. A full restart would fix it, but then I found a process called calendaragent and I would do the same thing I described above. Calendaragent is now gone in Ventura, but my guess is that exchangesyncd replaces it, as it behaves the same way. Hope this helps out!
I am on Ventura.
I deleted and re-added my Exchange account under 'Internet Accounts'
For me, that seemed to fix it.
Well, except for Apple birthdays.
But interestingly, Exchange birthdays may be working. I had given up on that ever working.
I also tried to remove the Exchange account, then I restarted the macbook and finally I added the Exchange account again among the "internet accounts": it actually seems to work. Calendar syncs with Exchange again!
Having this same issue after the Ventura update. I have 3 separate Exchange accounts configured on my Mac. 2 of them are low volume departmental accounts, and the 3rd is my own individual account. The departmental ones are operating just fine, but my individual account is not working right. No updates show up in Calendar. Most* calendar invitations/cancellations are showing fine in Mail, and if I click accept/reject on an invitation or OK on a cancellation, my actual calendar is updated as viewed in Outlook or the Exchange web interface, but no updates are shows in the Mac Calendar app at all. I turned off Calendar capabilities for that account in System Setting, which resulted in all of the entries for that account disappearing from Calendar completely, but nothing ever reappears even with the exchangesyncd process downloading gigabytes of data over and over again.
*as a side note, it appears that invitations that are generated by the Zoom Outlook plugin for Exchange (ie, invitations I receive from Outlook users with a Zoom meeting scheduled) are not recognized by Apple Mail as containing an actual invitation, so I can't even accept/reject those invitations using Apple Mail.

i actually deleted and re-added my account in 'internet accounts' and it seems to be working fine on ventura 13.0.1.
also have outlook installed, pointing to hotmail. That calendar has always been pretty accurate so I didn't really notice the iCal issues until a few weeks ago.
most new Apple releases lead to one or more of the following year issues: one or more calendars not synching, Apple Watch not working in Fitness plus and my made for iPhone hearing aid call routing getting messed up. Apple please fully test all these things before a new release.
All, I have now tried all suggestions including the one by TomixM and now seem to working again after a couple of stressful weeks. thank you to all.
In addition to TomixM suggestion, I also restarted, deleted the 365 account from my MacBookPro, added back in the account, left is a bit and after about 30 mins or so it started to sync, phew..
I finally bit the bullet and completely deleted my Exchange account, restarted the computer, and added it back in. It's going to take probably a few days to completely download everything again, but at the very least it looks like my Exchange calendar information is getting downloaded. Will just be letting everything sit over the long holiday weekend, and hopefully by the time Monday rolls around everything will be synced and can stay synced. Fingers crossed.
This is the information I was looking for. In previous versions of MacOS I had a cron job that killed CalendarAgent every night to avoid the recurring sync problems. CalendarAgent quietly disappeared in Ventura and I thought I was losing my mind. Your comment solved the mystery for me. Thank you.
What TomixM mentioned is what also working for me. Restarting the exchangesyncd process make calendar work again. I found that every time I change wifi connection, I need to kill exchangesyncd so that calendar sync again. Don't know what make that process fail in the background.
Ventura - I have no problem with the calendars syncing. I can't get Contacts to sync. I have tried all the tricks above, to no avail. In Mac/contacts I can see all my subfolders, but none of the individual contacts. If I add a contact on the Mac/Contacts app it will add it to the Exchange contacts. If I edit that contact on the Exchange side, it will duplicate the contact in Exchange rather than edit the contact on the Mac/Contact side
This was an issue on Monterey (and apple has usefully decided to close that discussion, even though its still relevant, sigh), so I've come here to report that in the past week I now have automatic syncing working again. Between Monterey and Exchange accounts.
I was having to do the 'kill calendar agent task' to get a sync.
So someone has done something in the back end.
That might apply to ventura, but am reporting here for the reason stated above.
I had massive problems synching my work Exchange email account, with varying degrees of dysfunction across three or four Macs synching with the same Exchange account, on macOS11 and now on 12. I had to call in external tech support; they suggested disabling the IP-address tracking blocker in Mac settings/network. It immediately started working.
Not sure if there is causality here. That tech support is not an apple specialist. But for now, it appears to have solved the problem.
Apple doesn't read here in this user-to-user forum for feedback or suggestions. You can, however, let them know your thoughts here:
Type "cal..." and you should see it... In Activity Monitor of course.
Same thing happened with me. Also discovered that my zoom meeting invites aren’t getting sent because of this same issue. Ughh
Ventura not syncing exchange/outlook calendar entries
