I don't understand what I need to do and have been searching and wondering for over an hour now.

All I want is a link to a calendar I have created (on Outlook.com but have access to Outlook program) that I can share with a group of people. When I update it, their calendar gets updated on the next sync.

Seems to not exist anymore as I only have options to type email addresses, of which I haven't got time to do and don't have them all anyway.

Doesn't Gmail have this ability? But I don't really want to have to go through Gmail as I use Outlook for everything, and I guess there's no way to share the calendar with gmail (that will stay updated), then share a link to that calendar through gmail to everyone?

Any ideas?
