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 use the same account at work and at home to use office and outlook. Outlook at home has the sun & moon and dark mode functions correctly there but at work it does not. How can I fix this? If this is account related why is it that it functions correctly on one install but not the other?

    Both systems run Windows 10 Pro and are on version 10.0.18362. Both are using windows dark mode.

    You have to be on the Monthly Channel in order to assure you see it.  See Gabriel Bratton's comment above on Nov 14 for more details.

    You call tell which channel you are on by looking in your Office Account window (under File) in the About Outlook section.
