Using New Outlook on Windows for personal email, calendar, and contact management
I have the same issue.
When I copy/paste using keystrokes I loose all formatting.
When I right-click the mouse I only have "paste" and "paste with plain text" options.
There's no search available for 'copy/paste' or 'copy' or 'paste' in settings/options
There's no info online or even on the MS site for copy/paste with formatting for new outlook.
