Set Outlook to Always Compose Replies in a New Window

In Outlook 2013 the email replies are by default started in the reading pane. While this is great if you are looking for Gmail-like performance, for those who want to write emails like in an new uncluttered window this is more of a roadblock. One way to disable this is to disable the reading pane, but the reading pane can be rather useful. If you’d rather not disable it then there is a simple setting that will allow you to keep it around while making a new window the default for composing replies.

Seen below: The default setting in Outlook allows replies to be composed within the reading pane.

To turn off the setting open up Outlook options from the File ribbon and then browse to the mail tab. Scroll roughly 30% down the page and you’ll find the checkbox for it labeled “Open replies and forwards in a new window.” Be sure to click OK to save changes and exit.

Domain Environments

To make this setting the default across the board, there is both a registry fix and a group policy for it. The registry item will not exist by default, however Outlook does automatically add it when changing the setting in Outlook Options. It is found here:

  • HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Message\
  • disablereadingpanecompose
  • Hex value: 1

To at a later time enable it again, set the value to 0 to re-enable reading pane replies. If you would rather just download a pre-made version of this key, we have both below:

For group policy the setting can be found in a similar location, except it is under the Policies key. Here:

  • HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\Outlook\Message
  • disablereadingpanecompose
  • Hex value: 1

End Result

Once enabled, Outlook will open all replies in a new Compose window. This is the same behavior exhibited by Outlook in versions previous to 2013.
