I have won an Iphone!!!!
It has taken me nearly an hour to find and remove calendar spam! 10+ "events" appeared in my partners calendar, purporting to have come from me, but were not displaying in mine.
I had turned off add events from gmail, but they still got in from somewhere. I turned all settings on until I could see them, then deleted them.
If I could dump Google for this I would, but her indoors loves it, well until today and we need to share a calendar
