Is there a keyboard shortcut available in Outlook (2013) to format an email reply I am writing into plain text? (N.B. Unlike this questioner I want to maintain the format of the incoming message as I read it, but when I reply want a quick mouse-free way of converting to plain text.)
There is a keyboard shortcut, using the native ribbon structure in Outlook 2013, which will do the following to the REPLY mail ( You can read email in HTML)
This shortcut works, when you use the Pop-Out Compose mail.
Hit ALT + O + TP
Onetime pop out will appear for confirmation
Once you confirm it, the whole mail in the Compose window would turn to plain text.
Hope you like this solution.
