So I started using the calendar more and I noticed that I have some calendar groups named after old MSN groups that I was part of. After looking around I found that the normal delete these groups you go through the outlook 2016 app and right click on the group then clicking delete.
When I try to do this the delete option is greyed out.
With further research I found that there was a hidden page that allowed people to leave old msn groups through one drive but the wordpress page that showed me this seemed to have a different page to me.

So my question is does any body know how to leave these old MSN groups so that my calander groups are not cluttered with embarrassingly named groups ?
