• Next, click “Account” on the sidebar. On the right side, open the “Office Theme” dropdown menu, and select your desired theme. The default theme is “Colourful”.

To enable dark mode in Office,

• Select “Black”. It is the darkest theme.

The theme and background settings affect all Microsoft Office apps on your PC. They even affect Office apps on other Windows PCs if you sign into them with your account.

• Click “File” and then “Options”. While in the General category, click on the “Personalize your copy of Microsoft Office” section after which you click “Office Theme” box and select the theme you want.
