Despite all the collaboration alternatives in Office 365, email remains a common place for back-and-forth communication that sometimes becomes lengthy. How do you manage the large amount of information when you’re working with a long email chain? You can lose precious time scrolling up and down and trying to keep track of all the details.

While splitting your screen/window in your Outlook email reply doesn’t 100% solve the information overload problem, it does offer a solution for managing those long emails.

To split your Outlook email reply window into two scrollable panes, you’ll first add a command to the Quick Access Toolbar and then use it in replies. Follow the instructions in the video above, or:

1. From the File tab, select Options.
2. Select Quick Access Toolbar.
3. Choose Commands Not in the Ribbon from the “Choose commands from” drop-down menu.
4. Select Split and click Add >>.
5. Click OK.

The Split command will be added to your QAT. When you have an email reply, whether nested in your Outlook window or popped out into a new window, you can select the Split icon and the body of your reply will be split into two scrollable screens.
