How to Change the Font Size of Email Content in Office 365 Outlook client

To be honest, the UI of Office 365 Outlook doesn’t get any improvement except for the ‘Focus View’. There are difference places you can change the view, fonts, layout…etc, which is quite confused.

Anyway, if you just want to change the font size of the email content, here is how.

In the right-bottom, there is a little tiny Zoom in/out bar:

By clicking the “+” or “-”, you can enlarge or shrink the fonts of the current email’s content temporarily, yes, temporarily, and only for the current email opened in the pane, only for this time.

If you want to change the font size permanently, click the percentage number (I circled it in red), a dialog box will pop up:

edit the ‘Percent’, and click OK.

Hopefully this wiki saves your time.
