Long time Mac user and I found the same problem when I updated my computer and laptop to the latest OS - Ventura.
While my phone still was able to see and manage events and invitations, the Mac was blank. Long story short - I removed the 0365 account and then restored it (userid / password) and after a 30 minutes or so, my calendar events all repopulated and I continue as before. IDKWhy I had to go through this extra step, but everything is working as expected now. Note: Mac Mail never had a problem with the transition to Ventura, only Calendar. Happy to help you Mark if you direct email me. > On May 23, 2023, at 7:00 AM, nanog-requ...@nanog.org wrote: > > > ** External email - Please consider with caution ** > > > Send NANOG mailing list submissions to > nanog@nanog.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.nanog.org/mailman/listinfo/nanog > or, via email, send a message with subject or body 'help' to > nanog-requ...@nanog.org > > You can reach the person managing the list at > nanog-ow...@nanog.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of NANOG digest..." > > > Today's Topics: > > 1.
