Thanks to both Emc and Sgunhouse for your quick replies.

I have recently installed Opera Mail Version 1.0 Build 1044 onto my Windows 10 Home Premium X64 latest Version 1607 Build 14393.693 to gain better sorting capabilities than I can receive with Gmail. Can anyone tell me how I go about enabling the Remove From View function on the Delete Menu? I have searched the Registry, but did not find any menu settings. Also, I looked at the configuration files for Accounts in Mail and found an entry of Permanent Delete=1 and since this was one of the options on the Delete Menu I tried resetting it to Permanent Delete=0 and restarted my computer but Remove From View still remained Grayed Out. Any help would be greatly appreciated.
