Microsoft Office supports dark gray and black themes. Office apps won't be affected by Windows 10's systemwide dark mode. However, you can choose a dark theme for Office apps such as Microsoft Word, Excel and Outlook.
Microsoft will only allow you to use Office Dark mode if your Microsoft 365 subscription has expired (formerly Office 365). Official 2016 and Office 2013 can alter your theme to 'dark gray'. This is compatible with all Windows versions, including Windows 7, 8 and 10. Unfortunately, Office on Mac does not offer dark subjects.
To change your theme, click the "File” menu at the left-top corner of any Word, Outlook, PowerPoint or Excel application.
