Exchange Calendar Stopped Syncing in Ventura April, 2023 I know there was a MacOS Ventura bug in December but we upgraded in March and it was working and stopped. We are currently on the latest release: 13.3.1. You can toggle the Apple Calendar off, and on, it will sync back up to a current steady state but will never incrementally sync again. For Monterey, I used the cron job: */5 * * * * launchctl stop com.apple.CalendarAgent && launchctl start com.apple.CalendarAgent ( not mine but copied from awesome people on the forum) it worked very well. In MacOS Ventura com.apple.CalendarAgent no longer exists and was replaced by exchangesyncd ( at least that's what I found no one spells this out please correct me if I'm wrong) will this work: */5 * * * * launchctl stop exchangesyncd && launchctl start exchangesyncd I also, need to quit the calendar via a cron job, force quit Exchangesyncd, restart exchangesyncd and then restart it. Anyone run into this issue with the latest Ventura? Any work arounds? Yes, I removed the account, toggled calendar on and off and re-added, deleted the cache, and rebooted many times. Can someone please help here this is affecting many our our power users who swear by AppleMail and won't use Outlook except as a workaround? Apple so far has no official acknowledgment one way or the other if the original bug was fixed but as I said it worked for 6 weeks and just stopped on 4/16/23. As always, thanks in advance

A recent thread here had a similar problem to yours and a solution was posted. I hope it might also work for you.

See the comment from TomixM where he describes how he used the Activity Monitor app to restart a process which then saw the Calendar app sync again.

Thank you David. Following this thread and also deleting and re adding again the 365 account seem to have it working.
