How can I make Outlook 2010/2013 always reply in plain text?

I want to be able to reply in old-fashioned plain text format when people send me emails (so I can reply inline). Outlook 2010 doesn't seem to allow this when the person sends me an HTML email.

Is there any way of telling it "No, really, all my emails should be plain text, and use ">" to prefix things I'm reply to."?


Solution 1:

Got there! To do so you need to read emails as plain text - which is available under:

  • File
  • Options
  • Trust Center
  • Trust Center Settings
  • Email Security
  • Read As Plain Text.

This means they all appear as plain text, so replies go out as plain text, which means that you get proper indenting (using ">") if you've set that up.

You can still display the HTML original for messages where you want to, by clicking on the "This message was converted to plain text" message on the header and switching to a different format.
