Adding Outlook Profile to Windows 10

Right click on the start button, select Control Panel (This is no longer an option as of Windows 10 version 1703). To access the control panel in versions greater than 1703, left click the start button and type "Control Panel". Then select the Control Panel from the search results in the start menu.

Change the view to "Small Icons" with the dropdown in the upper right corner of Control Panel.

Click "Mail" and then select "Show Profiles" to configure Outlook profiles.

If other profiles are added, make sure to check the "Prompt for a profile to be used" option in the Mail configuration window. This will allow you to switch back and forth between profiles that exist on your computer.
