Frequently Asked Questions

Why did the Dark Gray theme suddenly change in Microsoft 365?

Microsoft regularly updates the user interface for Office 365 applications. A recent software update altered the color palette and background contrast of the Dark Gray theme, unintentionally causing it to appear washed out for many users.

Can I roll back Microsoft 365 to a previous version to fix the theme?

Yes, it is technically possible to revert to an earlier build of Office using the Office Deployment Tool. However, this is generally not recommended as you will miss out on important security updates and bug fixes.

Is there a way to make the interface fonts bolder in Office?

Currently, Microsoft Office does not offer a native setting to adjust font weight exclusively for the application interface. Submitting feedback through the Microsoft Feedback Hub is the best way to request enhanced accessibility and font options.

Does the Black theme have the same washed-out issue?

No, the Black theme retains its high contrast and deep background colors. It is unaffected by the update that altered the Dark Gray theme, making it an excellent temporary alternative until Microsoft releases a patch.
