How can I attach email to Calendar in new Outlook?

I second that this feature is necessary! :)

Pain in the rear but this works!! Thank you!!

This indeed is very helpful. However, it does not solve the problem of saving an email in a folder. I used to right click on the email item in the email list, copy and paste either to a calendar event or a folder. But now it takes more steps to accomplish the same tasks.

Can Microsoft team help bring the previous functionality back PLEASE?

I just found a solution I think!

I went to the top and selected "forward as an attachment" - then it pulled up a new email with the attachment. So then I just grabbed the attachment in the new email and dragged it into the calendar event I was making.

Thank you for sharing this! While much more cumbersome than my old way of ctrl+c/ctrl+v at least that works for the meantime. It would be so much easier to just return the previously functionality that clearly a lot of us used all the time.
Edited to add: and when you do this method you need to go into your drafts and delete the email that created the attachment :|
