You can filter and locate messages in your mailbox by using the new Instant Search function. You can create virtual Search Folders that automatically update to display messages meeting certain criteria.

You can group and sort messages by sender, time, subject, size, category, or any other field.

You can assign color-coded categories to messages, tasks, appointments, and other Outlook items, and then group and sort items by color category. You can use the default Outlook categories or tailor them to fit your needs.

You can create folders to organize your mail, and move items to folders manually or automatically.

Outlook automatically archives old and expired items to a separate data file. You can specify the AutoArchive frequency, location, and other settings on a global and per-folder basis.
