Categories let you easily tag, label and group messages in Outlook on the web and new Outlook. Choose from default categories or create your own, and assign one or more categories to your messages.

Other people won't see the categories you assign.

Note: If the instructions don't match what you see, you might be using Outlook.com or an older version of Outlook on the web. Try Categories in Outlook.com or Instructions for classic Outlook on the web.
