VerboseOutput indicates to the server that it should give more detailed information than with a regular finger query. 

VerboseOutput is used in the Finger method, and causes the '/W' token to be added to the Query prior to connection and transmission to the Finger server. 

The default value for VerboseOutput is False, as assigned in the Create method. 

Verbose output may not be supported on some finger server implementations, and may result in the query being rejected by the server.
