How to Edit Category Colors for MS Outlook Email and Calendar

Change category colors to improve visual presentation with only a few clicks. Applies to Windows desktop, Mac desktop, and Office365 web versions of Outlook.

Categories within Outlook make it easy to group related items -- emails, events, people -- so that they're easier to find.

Applying colors (or editing the default color selections) allow you to more easily spot and recognize related items at a glance, to improve efficiency.

This document provides the step-by-step instructions to edit category colors to your liking.

(Note: Color selections are defined "locally" on an individual's computing device or within a specific account on one. Tagging an item with a "purple" category on your device and sharing the item with someone does not guarantee that it will be "purple" on their device. Unfortunately, due to limiations within Outlook, there is no way to automatically synchronize color information from device to device.)
