How can I delete a spam calendar invitation without replying?

You might try just selecting the event and pressing the delete key. You would normally get a prompt with the option to delete without notifying:

I'm running Mavericks too (10.9.4). I'm not sure why it isn't giving you the option not to notify. Also, as you discovered, with Mavericks I don't think it's possible any longer to have both an On My Mac and an iCloud calendar. You can create one or the other, but not both. But even if the calendar was local rather than iCloud, I would still think the notification would happen since it doesn't care where the calendar is stored. I guess I'm not sure what you can do except delete and notify, or leave the event on your calendar.

Randers, I've never seen the dialog box that you show when deleting unwanted invites from iCal -- I only see the options that Matt shows. I've been running everything from OS X 10.1 through 10.10. I too only get the option of "Cancel" or "Decline", the latter sends a message to the inviter whether or not you want it. It used to be that I could take my computer offline, delete the message and take it online again. But in later OS versions, the email gets sent as soon as you take the machine online again -- very annoying.

I wonder if the reason for the discrepancy has to do with the type of email server that sent the invite. iCalReplyChecker (www.nhoj.co.uk/icalreplychecker/) purports to add a dialog that gives control over whether the email gets sent automatically, but not if the invite was sent by Exchange or CalDav servers. (It is also out of date at this point, so I haven't tried it.)

Agreed!

The option not to notify no longer exists..

However, You can still do it by creating a new calendar, name it 'junk' or something, switch the spam invitation to that calendar (no need to accept or decline), then delete the new calendar; at this point, you will get the option not to notify...

This spam issue is getting very very problematic

i'm getting multiple spam invitations every day from chinese-looking sources (Chinese characters, and email addresses like: wjskdn6g@icloud.com)

The worse part is that i have no idea how they're getting through to the calendar since i do not have email enabled on any device for this iCloud account!!

This is very disheartening because i cannot figure out how these invitations are getting to my calendar!

Also, the big risk, if you deny just one of these invites, is that they will immediately know that your email address is connected to a real person, and that their spam got to you!

This is great news for a spammer, terrible for you!

Has there been any update from Apple on this? I am still having a problem with spam invites in Calendar and it seems to have been going on for several years now. Usually Apple is quicker about addressing issues like this. How can we reach out to Apple to get feedback on this?

Agreed. Having the same problem. Seems ridiculous to have to create a new calendar and delete it to deal with this problem that seems to be an Apple security issue.

Nice to know this problem has been persistent for 2+ across multiple operating system updates. Definitely still a problem in El Capitan, I haven't checked it this in Sierra though. I've been getting about one a day... HELP APPLE!

Thanks for the tip, this is what I did when I got this invitation to partake in a sale on RayBans & Oakleys in order to delete the event without notifying the sender.

Then I disabled Calendars and Reminders in my iCloud account System Preferences.

PS - I was also a target of the iMessage Chinese spam hack, where they used my iMessage account to send spam messages to China. Another iCloud security failure. I enabled two-factor authentication after that hack.

I do need some new WAYFARERS though.

I've also received a Chinese spam calendar event yesterday (which is set to repeat every day, with no end date!). The event was in my "iCloud Family" account, and therefore couldn't be moved.

Some tips - both failed and successful:

✖ I un-hid the Library folder, found the message and deleted it; that didn't work; I deleted the cache; that didn't work. I tried multiple times (with the Calendar closed, and even wifi turned off). Still no success. It kept re-appearing.

😕 Then on my phone in "Settings" I turned off "calendars" for my iCloud account, and it offered to delete all events on my phone associated with that calendar, which I accepted. I then re-enabled the calendar, and the event had gone from my iPhone ... but it still showed in my Calendar, and oddly, also in iCloud.

✅ What finally worked for me was to:

- print out the calendar for the next 2 weeks (where I added stuff yesterday)

- go into iCloud through a web browser, go into "Settings", and "restore my calendar from an iCloud back-up" to what it was before yesterday's spam

- add back in the odd event that had been lost in the process

✅ While in iCloud I also went into the "Advanced" settings of the Calendar, and selected the option to have invitations sent by email, and not automatically added to my calendar.

✅ As a preventive measure, also I turned off "auto add events" in the Calendar preferences, on both the Mac and iPhone

Hope that helps ... until Apple fixes this

Thanks --that works!

I just saw that RayBan ad pop up without any other associated information.

As soon as I turned off contacts and calendar in iCloud it disappeared without me having to decline, delete, or respond.

I'm really surprised that this is still a problem after so many years. I found comments from 2012 about this same issue. I have submitted feedback to apple with the hopes that they address it at some point.

This method does indeed work.

There is a workaround for this:

- Create a new iCloud calendar (e.g. "spam dummy")

- Move the event of the spam invitation to this dummy calendar

- Delete the dummy calendar. iCloud will now ask you whether you want to delete the events in the calendar with or without a notification to the sender (as it did until some time ago with individual invitations as well).

Nonetheless this should be addressed by Apple as currently there is no way to prevent such spam invitations. Even if an invitation is not spam I would like to be able to not send a notification that I deleted it.

After much research I found the perfect way to stop all these iCloud calendar invite spams.

Log in to iCloud on the web, open your calendar, and go to ⚙ > Preferences. Under Advanced, you’ll find an option to receive calendar invitations by email instead of straight into your calendar.

Now you can just "Junk" any emails that come in for this and leaves your calendar alone.

This suggestion came from http://apple.stackexchange.com/a/259750

Despite my post from 2 weeks ago, yesterday I had the Ray Ban ad pop up in my Calendar. I repeated the steps above, and cleared it quickly.

I was puzzled as to why it had still added automatically, and then found one more step I'd missed ...

✅ Go into Mac Mail > Preferences > General > Add invitations to Calendar ... needs to be set to "never"

Hopefully that's the last step ;-)
