The Mailbox displays all the items you have received, with the exception of scheduled items (appointments, tasks, and reminder notes) you have accepted or declined. By default, scheduled items and tasks are moved to the Calendar when you accept them.
Your received items are stored in your Mailbox. You can quickly change what is displayed by clicking a setting in the Display drop-down list. You can further restrict which items display in your Mailbox by using Find. For more information, see Finding Items in a Folder.
You can organize your messages by moving them into folders within your Cabinet, and you can create new folders as necessary. For more information, see Using Folders to Organize Your Mailbox.
You can also organize your messages by assigning categories to them. Each category displays as a different color in your Mailbox. You can search for categories. For more information, see Using Categories to Organize Items.
