How do I change my outlook theme in office 365?

Microsoft Outlook offers a variety of themes that allow you to customize the look and feel of your Outlook interface. Themes change the background color, text colors, buttons, and other visual elements in Outlook. If you use Outlook through Office 365, changing your Outlook theme is easy to do right from the settings menu.

Why Use Outlook Themes

Outlook themes allow you to personalize your Outlook experience and make it more visually appealing. The default white background can be harsh on the eyes for some users, while others may just want a more colorful or professional looking interface. Themes give you control over the look of your Outlook without having to make major changes to the layout. Here are some key reasons to use Outlook themes:

  • Make Outlook visually engaging – Themes liven up the interface with color, images, and other design elements.
  • Reduce eye strain – Darker themes can provide a better viewing experience and reduce eye strain.
  • Customize your workspace – Match your Outlook theme to your personal style or company branding.
  • Highlight important messages – Use color themes to make key emails stand out.
  • Organize your inbox – Separate different types of messages through color-coding with themes.

Outlook Theme Options in Office 365

Office 365 users have access to a wide selection of pre-made themes that are easy to browse and activate. Here are some of the theme options available in Outlook for Office 365:

  • Colors – Choose from various background colors like blue, green, red, gray, and more.
  • Textures – Add visual interest with textures like diagonal lines, circles, leaves, etc.
  • Outlook modes – Pick a Light, Dark or Black theme to reduce glare or eye strain.
  • Seasonal themes – Enjoy themes tailored to seasons like Spring Blossoms or Winter Snow.

  • Nature themes – Relax with themes featuring landscapes, plants, and animals.

Microsoft frequently adds new themes to choose from, so you can regularly change your Outlook for a fresh look. There are also third-party tools and services that offer additional Outlook themes beyond what Microsoft provides.
