Hi @Julien St-Pierre Fortin ,
Please refer to following code to get PersonProperties
string serverUrl = "http://serverName/";
string targetUser = "domainName\\\\userName";
// Connect to the client context.
ClientContext clientContext = new ClientContext(serverUrl);
// Get the PeopleManager object and then get the target user's properties.
PeopleManager peopleManager = new PeopleManager(clientContext);
PersonProperties personProperties = peopleManager.GetPropertiesFor(targetUser);
clientContext.Load(personProperties, p => p.AccountName, p => p.UserProfileProperties);
clientContext.ExecuteQuery();
