Microsoft suggestion calendar virus

My iPhone calendar has a ‘Microsoft suggestion’ that is spam/virus. How do I remove this? I tried checking for rogue calendars under my calendar settings but there is nothing showing up there. I have installed the latest security update to my phone.

There are now four people asking about calendar spam in this thread and the answer is the same

  1. Remove the subscribed calendar then
  2. work out the source of the infection.
  3. If it comes back post your own thread with screenshots.


I helped with 1. now you need to work out 2. for yourselves or go on to 3.

I did and there is nothing under subscribed I don't recognize. I unchecked all notifications on my calendar so it's not there . I'm just worried it's still sitting on my phone someplace since I tried shutting off before and it came back. I usually say no to spam or close it immediately so I don't know how this one came thorough. Hopefully this time it stays off my calendar. Thanks for trying.

Unfortunately there are no rouge calendars. However, I have realized that when I receive one of these, it is identified as a Category call "Microsoft Suggestion". Yet, when I go to edit categories, it does not show up. I'm confident they are spamming these invites, and when you decline them, they know its an active email. Any additional thoughts to blocking these ?

You will have to selectively remove calendars in the Calendar app (at the bottom tap on Calendars) until the calendar with the spam is identified, i.e. the invitation disappears from view.

Then see if it is a calendar you need. if you do then you will have to identify the source. Google has no more fixes than we have here.

Deleting all website data in Settings, Safari is always a good idea too.

I think the point that is being missed is that these unwanted meetings are coming into our base calendars. Not other subscribed calendars. Most of us who use our calendar, either a. Can’t delete it or b. Assume that if we did, none of our info would change, so that work would be futile. How can we block meeting requests from hitting our calendar directly?!

The point is not missed.

All we can do in this user forum is tell you how to get rid of spam subscribed calendars. You avoid them by not accepting website notifications.

However if these invites are on your “real” calendar you will need to find out why the calendar is receiving the spam. Your phone is simply reflecting your base calendar.

This is much rarer and outside the control of the phone.

Try Microsoft support.

Or migrate your existing appointments to iCloud calendar and ditch MS as your prime calendar source.

That is great is Microsoft calendar is not your mail calendar, but if you choose to use MS calendar and it is being infected then tracing the source is still necessary.

You should have only the Calendar, Contacts, Notes and reminders turned on for the accounts that are using them,

Or change to iCloud for everything like I did. (Migrating calendars needs the use of a laptop usually)
