I am using Outlook 365 1909 (Build 12026.20320) Monthly Channel. The Sun and Moon button was available in message's toolbar in Outlook for several days and now it is gone. No policies have been changed and system is restarted every evening. Microsoft Windows Version 1903 (18362.388) x64.

Thank you.

Hi all,

The Outlook Team currently has the Sun/Moon feature enabled in Monthly Channel Production at 10% of users.  It was enabled at a higher percent earlier until a bug was found.  The team wants to fix that bug before it gets turned back on for everyone.  If I can get an ETA on the rollout I'll post back with that status.

I experienced the same dark mode problem. May we know whether dark mode in outlook (with sun/moon button) is a beta feature or released feature?

If this is a released feature, why sun/moon feature is enabled in only 10% users ?

If this is in beta testing, why it is released in monthly production update?

    I came across this page from a web search. The sun and moon in the message window disappeared for me yesterday after having been present for months. I didn't change any settings. My Outlook theme is still set to dark and everything except the message window (reading pane mode) is indeed black, but the reading pane has turned white with no option to revert back to black.

    Don't really understand why this is such a mystery.  You would think there would be a definitive answer available.  Interesting how much more color in the icons, presence, and ribbon you notice when the background is dark.
