Using New Outlook on Windows for personal email, calendar, and contact management
I landed on this page because it was similar to my problem of not being able to cut and paste anywhere or anything in or out of the New Outlook. Upon changing back to the Old Outlook, I submitted the functional reason for reverting back to the Old Outlook and was given this solution to cut and paste. Go to Settings, General, Privacy and Data, Privacy Settings, then turn on "Optional Connected Experiences". After closing Outlook and rebooting, I am now able to cut and paste in and out of the New Outlook. I hope this helps some of you with the same struggle.
