Microsoft Launcher does not expose a documented policy or setting in Intune or its release notes that directly controls icon size on the home screen. The available configuration options focus on layout and appearance (for example, grid size, dock mode, folder style, wallpaper, and app order), but not icon scaling.
From the documented configuration keys:
-
com.microsoft.launcher.HomeScreen.GridSizelets admins define the number of rows and columns on the home screen, which affects how many apps fit on a page, but not the actual icon size. - Other keys such as dock mode, folder style, allow‑listed apps, and app order also do not change icon size.
If icons do not visually change when adjusting the size slider in the consumer app UI, this behavior is not covered by the available configuration documentation. For functional or design issues with icon size, the supported path is to submit feedback or a bug report from the device:
- Open Microsoft Launcher settings.
- Go to Settings > Help and Feedback > Report a bug.
This sends the issue directly to the product team for investigation.
