In Microsoft Outlook, open the Contacts screen.
Right-click or double-click a contact card and select Call Contact.

Note:
Numbers displayed in the Microsoft Outlook view and Call Contact option might differ. For example, if you use this procedure, you might be able to view only one number.

This is a known functionality.
