How do I block spam calendar invitation emails?

HI just to clarify you don't delete the calendar that you actually use. You create a new one andmove the event to that calendar, then delete that calendar. So the only event you lose is the one you don't want. Search the help pages for how to create a new calendar. It's very easy.

Thanks, hopefully this will help. I don't understand why this option is not also available on the desktop version of Calendar: Apple?

It is available on the desktop version 🙂

Sorry ChristopheP, editing, I posted that thinking you were responding to me.

On the desktop you have the option to not include events from apps, and I believe this does the same thing and will send any invites by email instead, which then gives you the option to block sender. Time will tell.

No worries. I just wanted to say that the exact same option is not available on the desktop like it is on the iCloud (Web) version. Yeah let's see if the iCloud web option helps.

Yes, but by doing this all of your legitimate calendar invites will also now go to email, rather than your Calendar. Not a great solution if you actually use the Calendar and Calendar invites.

Until Apple comes up with some other way you have 2 choices, spam events, or not. Which do you prefer?

True but I hate anything being added to my calendar without my permission so that suits me fine.

Just to add to the list, I started getting these, too, and to make it worse, even when I "decline" them, they show up on my shared calendar as "declined," and can't be deleted!

Apple, please give us some way to block calendar invites from anyone outside our contact list! This isn't Facebook; it's a work tool!

If you "declined" the event, as I and many others did the first time around, you can "show declined events" in icloud, and then just delete them by selecting and then hitting "delete" key. If they're in a shared calendar, note that you can only delete them if you're the owner of that calendar; declined events will still show up on the shared calendar for other users until the calendar owner deletes them.

This approach, plus the trick of turning off the option to see invites in-app, at least got me back to ground zero and cleared the Ray Ban and Ugg sales off my calendar...

There is one way to at least stop these from magically appearing in your calendar without your say-so. You have to make the invites go your email instead, where you can just ignore them, delete them, set-up rules to deal with them, etc.

To make the spam invitations go to your email, log onto your iCloud account on the web. Open the Calendar app, click the gear-shaped Settings icon in the lower-left corner and choose Preferences. In the Preferences box, click the Advanced tab, and under Invitations, click the button to have all calendar invitations go to your email account instead of your calendar. Click the Save button before you leave the screen.

I too am getting calendar events that have what looks to be chinese characters. I have searched my email and don't see them in the email, so how are they appearing in my calendar. I don't Accept or Decline. How are they appearing as part of my inbox event requests if they aren't in my email. How do I block them when I can't find the source of the invite? I found a post online showing how to make a spam calendar to associate them to and then delete it thus deleting the event. This is a bandaid and I've already received another invite request. Did you figure out where to block them?

Go to www.icloud.com>calendar>preferences and switch invitations from In-App to email

I managed to delete the spam invite after moving it over to a temp calendar that I created and then deleting the calendar; however, I'm running into another issue and haven't found a solution or work around. The issue is related to the spam invite...the spammer appears in the invitees list and I can't figure out how to delete it. I haven't seen anyone mention this, but I don't think it's just me. Could you please check the following on your iPhone or iPad?

1) Go to the calendar app and click the + as if you were creating a new event

2) Scroll down to Invitees and it should default to None

3) Click on None and it should take you to where you can add people

I have that setting already and I'm still getting spammed.

and there is no way to block the email address that is sending the invite.

you can't block the contact. Can you believe this was overlooked by the designers at Apple?
