Unable to delete calendar invites on my Calendar App after macOS Sequoia update

Hi, Yes, this resolves the current issue, but any new invite will stick as read-only, and you'll forever enable and disable it to get rid of these items. This is a workaround at best, and if you have a work calendar with thousands of items, the rebuild takes a long time, depending on server congestion.

Please keep it open; it's not a solution for enterprise customers. And yes, they love AppleMail and Calendar because Outlook or Google Calendar don't have this issue. It's a macOS issue. Why can't it toggle the read-only attribute via a terminal script?

This has been a really irritating issue. I'm on a listserv for work and whenever they send an invite (+ reminders) all of them clog my calendar even if I'm not attending that event. My Outlook calendar doesn't have that invite after I decline, and the email itself is deleted, but Apple calendar helpfully remembers and shows them to me.

This is so annoying

The VOID strategy works, but it's a real hack (albeit a clever one!). I was hoping Apple might have fixed this, but having just "upgraded" to 15.5 I see it's still broken.

I've tried the idea of adding the email alias to my contacts but this doesn't seem to have worked. Anyone who's got this to work, could you give us some more details? Is it the Apple contact list or the Outlook contact list?

I just want to thank you for suggesting this fix. This works, and I'll be using it from now on! You're saving me from my daily delete/undelete exchange calendar duties... I've been annoyed by this for months.

I have also experienced this problem. It happened to coincide with my upgrade to Sequoia...

I'm also experiencing this same problem and recently up graded to Sequoia.

Same issue. I've tried responding to events and deleting them and I just can't get them to go away.

While I don't know who wrote the Exchange connector on MacOS, I am willing to bet this to be an Apple problem.

This works!! I love you!

I did this, but it only works temporarily: unwanted calendar events will build up in future and you'll have to do it again. I had hoped it would fix the problem, but it only clears out the garbage.

I (bet that many other users) cannot adjust Username / e-mail difference (so they match) to account they do not own.

Agreed.

Agreed. Still the same 4 months later. I tried adding an email address to the contact card, but that does NOT work.

I have this problem. I have removed and re-added the account. But It dont seam to help. Other calendars google and iCloud works fine
