Categories, flags, and reminderscan help organize your email, calendar, and contacts plus create a to-do list.
To assign a category to an email, right-click the message, choose Categorize, then pick a category.
The first time you use a category, Outlook asks if you want to rename it. Otherwise it's named for a color. You can create a category by selecting New > Name > Color > OK.
To see all categories, select Categorize > All Categories.
You can follow the same process for calendar events and contacts. When creating meetings, select Categorize, then select your category.
Note: Categories are only seen by you, and you can add multiple categories to email, contacts, and events.
