The new Black Theme with support for a dark Reading Pane with the ability to toggle between light and dark (Sun/Moon button) got first introduced in Version 2001. Requirement 1: Only in Microsoft 365 Version 2001 and up The Sun/Moon button toggles between a white and dark Reading Pane in the Black Theme.

Only when you fulfill all requirements will you be able to turn the Reading Pane dark in Outlook when you have selected the Black theme.īy default, with the Black theme selected, the Reading Pane will show with a dark background and you’re able to toggle it between dark and white with the Switch Background command (Sun/Moon button) left from the Reply, Reply All and Forward commands. The ability to turn the Reading Pane dark in Outlook has a couple of requirements. How do I turn the Reading Pane dark as well with the Black Theme enabled in Outlook? I read that there should be a Sun/Moon option somewhere to toggle the Reading Pane dark too but I can’t seem to find it anywhere. This works well but the Reading Pane in Outlook remains white and creates a very bright contrast with the Black theme.

I’m a big fan of many applications offering a Dark Mode and I’ve also switched my Office theme to Black.
