Switch to Reading View to Display Equations

Changing your document view mode can often bypass Editing view rendering limitations, allowing equations to display properly.

Historically, Word Online has struggled with rendering complex formatting like equations while in Editing view due to browser limitations. Switching to Reading view processes the document differently and usually renders the equations correctly.

1
Navigate to the View Tab

Open your document in Word Online and click on the 'View' tab located in the top ribbon menu.

2
Select Reading View

Click on 'Reading View'. The document will reload in a view-only mode, and the gray "[Equation]" boxes should now render as proper mathematical equations.

Temporary Service Updates: Microsoft occasionally pushes updates that fix or temporarily break equation rendering in Editing view. If the issue recently started, it may resolve automatically after a future update.

Frequently Asked Questions

Will these grayed-out equations print correctly if I print from Word Online?

Yes, even if the equations display as gray "[Equation]" boxes on your screen while editing, they will usually render perfectly when you print the document or export it as a PDF.

Why does Word Online struggle to display equations?

Word Online is a lighter, browser-based version of the desktop software. Rendering complex mathematical typography in a web browser during active editing requires heavy processing, which sometimes causes display glitches or is disabled by design during service updates.

How can I report this rendering bug to Microsoft?

You can report the issue directly from Word Online by clicking on 'Help' in the top ribbon and selecting 'Feedback'. Describe the issue and mention your browser and OS to help them track the bug.
