I share a calendar across the family for each member, and I want to be able to put calendar entries on their calendar
I would like to create calendar entries on my kids calendars (like I can now with the old interface). I'm using Edge on Win 10, and I do not see a 'calendar' selection. This is required for me to use this calendar … please add this back!
