The 21 June 2019 Office 365 for Windows Insiders release 11815.20002 has a new Dark Mode feature in Outlook plus some fixes.

Here’s the details including Microsoft’s report on ‘Notable Fixes’.

Outlook

New features

Outlook 365 for Windows now has a Sun/Moon button when using Dark mode and the black theme,

Sun/Moon switches the reading and compose panes between a dark or light  background.  That’s a good move because while you might prefer dark mode, most readers of your messages will see it with a light/white background.

The light background looks like this.

According to Microsoft, enable this feature from File | Office Account | Office Theme and choose the Black theme.  For some reason the Sun/Moon icon isn’t appearing in our test machines.

There are some known issues with the feature, that should be fixed in later versions.

• First line of text is sometimes recoloring incorrectly when composing an email, but it should still send correctly.
• Text for a blocked image is unreadable.
• Text inside text boxes and shapes is being recolored when it shouldn’t.
