Update Word for Mac to the Latest Build

This specific layout dialog failure is a known software bug in version 16.46. Updating to version 16.46.2 or later permanently resolves the issue.

Uninstalling and reinstalling the application will not fix the problem if you are reinstalling the same buggy build (16.46). A direct software update is required to patch the missing dialog trigger.

Launch Microsoft AutoUpdate

Open Microsoft Word on your Mac. Navigate to the top menu bar, click on 'Help', and select 'Check for Updates' from the dropdown menu.

2
Install Available Updates

In the AutoUpdate tool, look for the Microsoft Word update (ensure it is version 16.46.2 or newer) and click the 'Update' button to install it.

3
Access the Layout Settings

Once the update is complete, restart Word. You can now go to Layout > Margins > Custom Margins, or Format > Document to successfully open the Layout dialog box.
