Can't delete spam invite on my iPad calendar

My wife just had this today. Apparently the source was as one other poster pointed out a deleted spam email. It was either in the trash file or the spam file and all she did was empty the file and it disappeared.

I was going bonkers trying to figure this out. But, all I had to do is clear the junk mail folder. This solved all my issues with spam invitations showing up on my calendar.

I hope this helps.

I added sender to contacts then blocked immediately. Then Click on calendar app, click back as far as you can go, select calendars, deselect all, select your calendars you wish. That fixed it for me. I definitely feel invaded

Same here, did you find the source of this?

I have had this recently too.

Press and hold the invite and select ‘cut’. Then press and hold it again and select delete. That worked for me.

I had this too and solved it! The meeting request got filtered into your junk mail. It’s sitting in there and you need to delete it, then delete again out of your deleted items.

I found the email, as you suggested. I deleted it from Spam and then Trash. Voila! The calendar invite disappeared. Thanks!

I'm having the same problem, I've tried everything but it won't go away. No idea where it's come from. Does anyone have any ideas?

does not work. no option to delete, only accept maybe decline
