-It's not possible to enter details (pictures, informations, ...)in a calendar entry because this field is missing.
-It would be nice to move and/or copy a calendar entry to another calendar
-Charms are missing.
In summary the old version is better.
Thank you for your feedback! The deployment for notes, enabling events to be moved between calendars, and icons in the Outlook.com beta is now complete. If you refresh, you should be able to see the experience.
