Change Calendar Groups
I am unable to change a calendar event into a different group. I was able to before but that functionality seems to have disappeared.
Thank you for your feedback! The deployment for enabling events to be moved between calendars in the Outlook.com beta is now complete. If you refresh, you should be able to see the experience.

If you go out of the beta, you can edit what calendar it is saved to and then switch back.
I painfully added three months worth of events...and then realized all but the first were on "my calendar."
