Context:

Microsoft Graph API is the service we use for our online Powerpoint player. Previously, the background color in the iFrame was white, it is now black.

Steps to replicate:

  1. Navigate to any slides resource

Observed: background of slides player is black

Expected: background of slides player is white

We didn't find a way to customize that color, is there any way to do it or could you implement that customization?

    The background color of the online PowerPoint player shown via Microsoft Graph cannot be controlled from Microsoft Graph or from the embedded iFrame.

    Available customization in the provided context applies to slide background and theme inside the PowerPoint document itself (for example, using the Eyedropper tool in the desktop app or setting backgroundColor on SlideBackgroundPatternFill via the PowerPoint JavaScript API). These options change the slide’s own background, not the outer player surface rendered by the online viewer.

    The change from white to black in the player background is therefore a behavior of the online PowerPoint viewer and not something that can be overridden or configured through Microsoft Graph based on the current documentation.
