Microsoft Outlook has many different features that benefit its users and their workplaces. While Outlook is a preferred choice of an email client for many businesses, its workplace-focused user interface can feel tedious. 

While themes can be purely cosmetic preferences, they can also help create higher contrast, easing eye strain and improving visibility while navigating your inbox. Luckily, users have options for their inbox theme, though the quantity is tied directly to which operating system you’re using and whether you’re on the browser site.

If you’re looking to personalize your inbox and make the whole experience more “you,” or want an inbox experience that’s easier on the eyes, you can change your Outlook theme through your account settings.

Here’s how to do it.
