If you find the text in an email too small, Outlook 2013 gives you the ability to zoom in and out as needed, with a Zoom slider at the bottom of the window. You'll notice, however, that if you leave Outlook and come back again, or if you move from one Outlook screen to another, the zoom resets to the default. While you can't set a permanent, custom zoom setting in Outlook, a couple of tricks can help you customize the way Outlook appears on the screen.
Drag the "Zoom" slider located in the bottom-right corner of the Outlook window. Dragging to the right zooms in, while dragging to the left zooms out. If you have a scroll mouse, you can also zoom in and out by holding down the "Ctrl" key while moving the scroll wheel forward and backward.
Click the current zoom level displayed beside the slider to open the Zoom window. In addition to selecting zoom presets of "200," "100" and "75" percent, you can specify a zoom level in the Percent menu.
Drag the border line separating the main window pane from the left pane to increase the visible area after zooming in. Both the zoom level and pane border return to their original settings when you leave. For example, simply moving from your inbox to Outlook Calendar resets the inbox zoom and the size of the preview pane when you return.
Go to any view in Outlook, with the exception of Contacts, to change the font size. The Contacts view doesn't have an option for changing fonts. Click the "View" menu and then the "View Settings" icon to open the Advanced View Settings window.
Click the "Other Settings" button to open the Format window, and then the "Font" button to open the Font window.
Select your desired font in the Size menu. You can also change the font and font style. Click "OK" to close each of the three open windows and to save your font size preference. Changing the font in one Outlook view doesn't affect the other views. For example, if you want to change the fonts in Calendar and Mail, you need to change both separately.
Tips & Warnings
