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?

    Is the existence of the button even related to build?  Why is this so mysterious?  If you have the black theme on, and Win10 in dark mode, it's absolutely ridiculous to have a white background reading pane in Outlook.

    I'm beginning to wonder the same thing. I think the change has been pushed out to my machine, but something is stopping it from turning on.

    Here's a possible x-factor... My company hasn't pushed out Windows 10 major updates yet, so I'm still running 1803... so I don't have system-wide dark mode on Windows 10, which I believe was a 1809 change.

    While I believe it's ridiculous to be able to enable dark mode on Office generally, but only have the reading pane be dark if system-wide dark mode is enabled, I'm wondering whether there's a conditional buried in there somewhere that is preventing it from coming on.

    Just a thought, since at the moment I'm scratching my head too.
