Outlook deletes an email when I am in quick reply and try to delete text

I am having a problem where when I use quick reply and hit the Delete, the email I am working on is deleted. What I am expecting is for some of the text to be deleted, as in older Outlook or any other text editor.

I have tried this on other computer running outlook 2013 and there it works as I would expect. If the reply has focus, the email is not deleted, and instead the text is.

I know it is not a keyboard problem (button stuck) because the problem occurs if I RDP into my machine from a machine on which this issue does not exist.

Incidentally I also cannot Ctrl+C from outlook. It works everywhere else, and normal copy from outlook using right click works. I do not know if this could be related.

Just in case anyone else experienced this...there is a setting in Outlook 2013 that you can uncheck to fix not only the issue of the Delete key deleting emails but also the inability to use CTRL+C to copy text from emails.

Go to File -> Options -> Mail. Under the "Outlook Panes" heading, click the button for Reading Pane. Uncheck the box for "Single key reading using spacebar". Click OK to save that change.

You should now be able to delete text with the Delete key while using in-line replies, and you should also be able to copy/paste. You will no longer be able to use the spacebar to move between messages in your folders.

I only had to close and then re-open Outlook and that fixed the delete key issue. On a side note, I find that with the vast majority of Outlook problems, a new Outlook Profile fixes just about all of them. I hope this helps.

Running a full repair on office fixed both problems. I do not think this is a great solution as it is rather time consuming, but it works. Also is odd as the problem started from the point of original instalation

Sounds Silly but I have noticed this behaviour in the 'Docked' reply windows with some keyboards. The delete action operates on the message instead of the text.

Undock the reply message. The delete key functions as expected. I believe this behaviour is actually different with different keyboards.
