If you want to take advantage of Outlook 2013’s security features, the first step to take is to get yourself a Digital ID. If you work in a large organization, your employer may have gotten that for you. If you want to get a Digital ID for your own use, you can get one from a company that issues and maintains Digital ID services by following these steps:
Click the File tab in the Ribbon.
