Outlook 2016/2019/365 Fonts


When setting fonts in Outlook for macOS, there is no way to change the display fonts, only the compose fonts.


Font settings may be set and changed from the command line.

Display font of plain text messages too small? Do this to change it to 13 point Andale Mono:

1) Close Outlook

2) Open a Terminal window and run this:

defaults write com.microsoft.Outlook PlainTextWebPrefsIdentifierWebKitStandardFont -string "Andale Mono"

defaults write com.microsoft.Outlook PlainTextWebPrefsIdentifierWebKitDefaultFontSize -int 13

Please note that simply opening Compose Fonts settings will reset the Display Fonts settings, requiring you to re-run the commands from the terminal.
