2. Click the People button located in the bottom left corner of Outlook.
3. Once the ribbon has adjusted to reflect contact options, select the Folder Tab and click the Open Shared Contacts icon.
4. Type in the Username or click to locate the user that has shared their contacts with you. Once their name has been selected, the shared folder will appear within the left-hand panel under Shared Contacts.
