Hi Don! My name is David and I’m here to help.
I understand that you're having trouble with copy and paste in the new Outlook. It can be frustrating when you're unable to directly copy documents from Explorer and paste them into your email. In the old Outlook, it was much easier for you to do this.
In the new Outlook, the process is slightly different. Rather than directly copying and pasting from Explorer, you can use the "paper clip" icon above the email composition window to attach the file you want to send. I know it can be time-consuming to search through Explorer to find the exact document you want to copy and paste, especially if you have a lot of files.
If you prefer to do it the old Outlook way or in the "Classic" format, I'm afraid that's not currently possible in the new Outlook. However, you can still attach the file using the "paper clip" icon and send it as an attachment.
I hope this helps clarify the process for you.
Thanks.
