Using New Outlook on Windows for personal email, calendar, and contact management
HERE IS THE FIX TO THE PROBLEM:
I had the same issue as the Original Poster! Rather than right clicking and "Copy" email to "Paste" as an attachment in a new email you must:
- "Pop out" the email you are drafting into it's own window
- Find the email from your inbox you want to include as an attachment
- Drag and drop the email from your inbox/outlook location to the draft email and it will be included as an attachment
