You can enable dark mode in Dynamics 365 and model-driven Power Apps by adding a URL parameter to your browser address bar.
Whether the motivation is reducing eye strain, working in low-light environments, or simply preferring a darker interface, this is a frequently requested feature.
Microsoft has not officially released it, so it comes with limitations: the setting does not persist between sessions, some custom controls render incorrectly, and certain elements remain in light mode.
This article and accompanying video explain how to enable it and document the issues we found during testing.
Enabling Dark Mode
Add the following to your Dynamics 365 or Power Apps URL:
&flags=themeOption%3Ddarkmode
Your browser will reload in dark mode on desktop or mobile devices.
Regular interface components such as charts, dashboards, grids, controls, ribbons, embedded Teams chat and the site map will now be displayed in dark mode.
An alternative version is also available:
&flags=themeOption%3Dteamsdark
The main difference with this variant is that grid links, buttons, and icons are formatted in purple instead of blue.
Dark Mode Limitations
This experimental feature is unsupported and has some limitations.
Our tests show that dark mode does not apply to the following, which remain in their default light display.
- Sales accelerator work lists and sequence designer.
- Pipeline and focused views.
- Embedded Power BI components, including visualise this view and sales usage reports.
- Various screens in Real-Time Journeys, including designers for segments, emails and journeys.
- Some inbuilt chart displays.
- Some custom Power Apps Component Framework (PCF) controls.
- App selector.
Saving Dark Mode
Dark mode settings will not carry over between sessions. To save it, you’ll need to bookmark the revised URL for your app, including one of the above additional query parameters to enable dark mode.
