Right Click Copy to Folder. In OWA for Exchange 2010 you could simply right click a draft and select "Copy" then "Copy to folder" to make a copy of a draft. The process has now been complicated by removing the "Copy" option from the right-click menu, and some users would like to see this option brought back for the latest version of OWA.

Exchange 2010 OWA method:

Open the Drafts folder.
Find the specific template in Drafts
Right click on the message and click “Copy to Folder”
Click “Copy” again.

A copy of the draft will appear below the original draft.
