Change your default font

You can now customize how your messages appear by changing your default font. When you create a new message or reply to an existing message, your text will appear in the font, size, color, and emphasis you've selected.

To change your default font, select Settings The Settings button > Default font.

Use dark mode everywhere

Dark mode now works in the reading pane and calendar items. Dark mode changes the default bright background color to a darker color, which is easier on the eyes in low-light environments or if you prefer less bright interfaces.

To turn on dark mode, select Settings  The Settings button > Personalization, and select Dark mode. If you want to view a particular email or calendar item in light mode, select the Turn on the lights icon to toggle dark mode on or off for that item.
