Organize your inbox and categorize your emails. Categories make emails easier to find. For example, set up categories for emails that contain certain words in the subject line or specific recipients in the Cc line. Then automate categories by creating a rule so that Outlook.com applies the category you want when the message is delivered to your inbox.
