Question: Spam Calendar Invites

In just the past week, I have started getting spam in my calendar.

Now, I have looked all over the net and most of the previous discussions and how-tos involve preventing calendar items from getting passed from Mail.app to Calendar.app. I do not believe this is happening. I have Mail.app set to not send to Calendar.app. I am not seeing any spam mail in the Inbox of Junk box. It's just coming straight to the Calendar.app.


When my wife sends a calendar event to me, I do not get any sort of email, just the invite in the Inbox of the Calendar.app. So that's how these are coming in. Probably straight from a spammer using a Mac on iCloud.


How do I block these? There doesn't seem to be any way to do so.


Thanks

Came across this while digging around.


You can tell iCloud not to send Calendar Invites straight to the app but to instead send them to you as email. This will allow you to filter the invites through normal spam/junk filtering in your Mail client.


Here's how:

1) Go to iCloud.com and log in

2) Go to the Calendar

3) Click the little Gear icon in the lower left corner

4) Select "Preference" from the pop up menu.

5) Choose the Advanced Tab across the top of the resulting window

6) At the bottom, under Invitations, choose "Email to ..."

Now all your calendar invites will go to email so you can choose whether or not to send them to Calendar.app


Personally, I'd rather see Apple include some method for dealing with spam in the Calander, like the option I mentioned earlier: Check Box: Ignore invites from people not in my Contacts.


But, this will work for now.

I tend to agree with you since it´s all icloud-e-mail-addresses being invited. I wouldn´t be suprised if they used a random generator.


But did you see my workaround I bumped into?:


- create new calendar (call it "spam" i.e.)

- assign spam invite to that new calendar

- erase that spam calendar and there you are given the two options:

- erase + notify

- erase without notification !!!

Yes, but that sends a message back to the sender indicating that I declined it. Now he knows my email is legit and the attacks will continue and increase. I was hoping there was a way to delete it without alerting the sender, such a simple "delete" or "ignore" or better yet, "block."


Perhaps I wasn't clear enough in my original post.


I know it can be removed. What I want to do is PREVENT my Calendar app from even receiving these items. For example, a check box that says "Receive only events from known contacts" or some such thing.


Seems odd that Apple would leave this wide open back door of annoyance.

I do not see a way to delete it. Accept. Maybe. Decline. No delete. More info on the does not have a delete button, nor does pressing delete key on keyboard remove it.


Also, I already have two step. It's just someone spamming outgoing invitations to a list of people. Not unauthorized access of my account.

Delete it and consider changing your password to something stronger. Also consider enabling either two-step verification or two-factor authentication if haven't done so already.

Dear Andrew,


I fully agree with the suggestions you made and I´m glad you made them, because I´m getting more and more concerned. Still it remains a workaround as it just re-routes the spam to your e-mail. Best help would be as you said if Apple added the option to delete without notifying the sender. Best help until than would be changing the icloud.com-email-address, I guess. Would you agree?


I´m being harressed as well since one or two weeks. As a workaround I created a "junk" calendar to at least hide the invites, but now I keep getting this note everytime I open ical, that´s why I´m getting concerned it could be more than spam:

Translation: "server announces error.

The access to.....in "junk" in account....is prohibited.

Answer of server: "403" to process CalDav....

ignore/try again/use serverversion"


I clicked "ignore" for every invite I´m hiding in "junk", didn´t dare to click "use serverversion" even though I´m being curious.


Can you ease my concern?

Hi Susu,


I think you are right. I personally do not want to acknowledge the spam calendar invite by clicking Accept or Decline... At this point, the only option is to divert the invites to email and delete them before they make it to iCal.


I also noticed an option in the Mail.app settings that stops Mail.app from kicking calendar things to Calendar.app. You might want to make sure that is also disabled.


Mail > Preferences > General > Add invitations to Calendar > Never

Yes, I have two-factor authentication enabled with my Apple ID. It is amazingly annoying, especially when trying to use iCloud on the web (like from a work computer or something), but I suppose it is worth it.


I do not think this issue is on my end, nor do I think I've been hacked. It is definitely possible that my email address has been obtained one way or another. I've had it since the days when iTools first rolled out. It's been my main email all this time. So whether they got it from the myriad data breaches over the years or just from my own general use, IDK. Either way, I am fairly certain my Apple ID is secure.
