Unsolicited Calendar events appearing from emails

I was looking at my Calendar and noticed an appointment for a server migration. I do not work in IT.

I didn't click on the Calendar link, but went back to my Inbox and searched on the information that I could see in the unopened Calendar summary. Lo and behold, there was an email that I hadn't opened (knowing it was spam, or worse, a phishing scheme) with the same info.

Is this a known "feature?" I certainly don't want unsolicited mails with dates and times ending up on my Calendar. Isn't this a security thing, when anyone can send me an email with a date and time and it gets added to my Calendar without my consent or knowledge? Any advice appreciated.

iPad Pro, iPadOS 26

Then you need to:

Open the Calendar app
Tap the Calendar icon on the bottom of the screen
Uncheck the option for Siri Suggestions.

That should do it. Once you uncheck that, the events suggested by Siri will be immediately removed. It is a feature in the Calendar, but you certainly don't have to use it and can be easily turned off.

Apple also added another feature in iOS 27.2 to make it easy to exclude apps that Siri can use for information. For that, go to Settings > Siri > Excluded Apps, and add any app you wish. Those apps will then be excluded from Siri, Search, and Suggestions.

And for other Suggestions that appear in Search, on Home Screen and Lock Screen, you can go to Settings > Siri > Suggestions and turn off the global settings there or individually for the apps you choose.

The big question is are you syncing a Microsoft/Google email address to the Calendar app on your device. If so, those are being added to the third party calendar associated with the email address, such as Outlook or Google Calendar, and those will sync to the Calendar app no matter if you have read the email or not. Each of those 2 services have a setting when you sign into that Calendar on the web to prevent adding events to the calendar from emails.

The easiest way to test if they are syncing from that third party Calendar is to go to the Settings on your iPad for the Calendar app and under accounts, select that account and temporarily disable syncing. If that spam immediately goes away, then that means it was synced from that third party calendar associated with your email address.

This has happened to me since updating to iOS 27

What is VERY ALARMING is, this invite was added to my Calendar without my permission and MORE IMPORTANTLY it came from my Mail Junk folder

All official apple applications

Why would Apple allow anything from a Junk folder?

Why would Apple allow anything like this without permission?

Apple's Advance Tech Support seems unbothered by this and only offer options to disable a Calendar option

Now I am not able to use this function from people I trust

How do you get Apple to acknowledge that this is a Huge Problem?

No, I'm not syncing another address to my Calendar. This was a spam email sent directly to my iCloud address, and automatically added to my Apple Calendar app without my knowledge or consent. It was like "scraped" (right word?) by some kind of automated process and dumped into my calendar. That sounds really... unsafe.

I'd just like to add that some of these AI-driven processes were previously annoying but I'm going to start sounding the alarm when they are opening the door to malfeasance.

Thanks. I will give it a try but I won't really know for sure until someone sends me an unsolicited scam link again and I don't see it in my Calendar! That was the worrisome thing... that anything that gets sent to a person automatically appears on something that the whole family shares (for adding school schedules and extracurriculars, etc). A lot of stuff could go wrong when that's an "opt-out" rather than an "opt-in." It's like an invitation to scammers. Anyway, fingers crossed! Thanks again for your advice.

So why on earth do you assume this behavior is intentional by Apple and that everyone is experiencing the same thing? I’m not and I’m on macOS 27, iOS 27, Home Pod Software 27, 27 on everything.

Why would Apple acknowledge what you call a Huge problem when only a few users are reporting it under unknown circumstances? Chill out.

I get an occasional notification that an event has been detected in an email but I’m always asked if I want to approve it. Nothing ever shoes up without my allowing it.

I hadn't even opened the email. I guarantee you that I did not approve it.
