A networked system includes multiple information handling systems (IHSs) that store personal user information such as name and contact information. The networked system automatically updates personal user information when one IHS communicates with another IHS. A first IHS stores personal user information associated with a first IHS user. A second IHS also stores the first user's personal information. The first IHS sends a first user information update to the second IHS if the first IHS determines that the first user information on the second IHS is not current. A digital certificate accompanies the update to indicate the authenticity of the information update to the second IHS.
