You know how to open or pop out Outlook email replies or forwards into a new window, but what if you always want to do that? In other words, you’d want Outlook’s default behavior to be to always open replies and forwards in a new “popped out” window rather than nested into the Outlook window.

In Outlook 2013, it’s simple.

1. From the File tab, select Options.
2. Go to the Mail tab.
3. Scroll down to the Replies and forwards section and check the box next to Open replies and forwards in a new window.

In the Outlook Web App:

1. From your gear menu, select Options.
2. Click Reading pane under Layout.
3. Select Type in a new window under When writing email messages.
