How to remove an unwanted calendar invitation on my iPhone?

I received both an email and an invitation into my inbox of my calendar “Alert Trojan Detected” the calendar selected doesn’t have a delete option like all my other calendars. There is no option through accounts. How do I delete this?

Hi HelpMeNowPlease01,


Thanks for contacting Apple Support Communities!


We understand that you need some help to remove a spam calendar invite.


Check out this resource which will show you how to remove a spam calendar invite: Delete spam calendars and events on iPhone - Apple Support

"How to remove calendar spam on your iPhone in earlier versions of iOS

  1. Open the Calendar app.
  2. At the bottom of the screen, tap Calendars.
  3. Look for a calendar that you don't recognize. Tap the More Info button  next to that calendar, then scroll down and tap Delete Calendar.

If this doesn't fix the issue, delete the calendar subscription in Settings:

  1. Open the Settings app.
  2. Tap Calendar > Accounts. Or if you use iOS 13, tap Passwords & Accounts > Accounts instead.
  3. Tap Subscribed Calendars.
  4. Look for a calendar that you don't recognize. Tap it, then tap Delete Account."


We hope this helps you.


Cheers!

I'm having this too. It shows it's from my Hotmail Calendar. I go to hotmail calendar in web browser and there is no event. I can't find anything relating to an email for "ALERT! Trojan DETECTED" event. I cannot decline the calendar entry and the only way to remove it so far is to disable my hotmail/outlook calendar, which I obviously would not want to do. I tried updating to iOS17 to see if that helped and still nothing.

Same problem for me - all of a sudden my iPhone calendar was showing all day entries from 1st Nov to 27th Dec for this; unable to decline invitation or delete etc.

After going thru settings > Calendar > accounts, noticed that my outlook account (for which I use for email) was also set (via the green button) to sync outlook calendar. I deselected this option (but left email still active) & okayed warning from iPhone that it would delete the outlook calendar entries and lo & behold the suspicious entries have now disappeared from iPhone calendar! Never use outlook calendar anyway - only always the iPhone calendar so no loss not to synch with outlook. And it certainly seems to have sorted issue. Looks like problem is with outlook….

All you're doing from the above is not synching your outlook calendar onto your iphone. So the outlook calendar and entries will still be available via outlook / hotmail. un-synching outlook from the iphone seemed to work ok for me & solved issue. Guess you can then go into outlook calendar via hotmail etc and try to delete the entries directly from your outlook calendar. Once / if you've done this, then you can also reconnect your outlook calendar to your iphone to re-synch the calendars again. Although as I dont use my Outlook calendar, I haven't bothered with this step - just simply disconnected it from synching with Iphone & it has cured the problem. So from this, I assume this issue lies somewhere within Outlook / Hotmal?

I’m afflicted by the same issue.


Yes, deselecting the Outlook calendar removes the invitation from the iPhone, albeit at the expense of not being able to use my Outlook calendar with the iPhone.


The most bizarre thing I noticed, however, is that my Outlook calendar shows no such event or invitation. 🤷


Someone is VERY insidious.
