<1> Section 188.8.131.52.3: The initial release version of Exchange 2010 requires the settings:PhoneNumber element to have a value when the settings:EnableOutboundSMS element, as specified in section 184.108.40.206.2, is set to 1. Under these conditions, if the settings:PhoneNumber element does not have a value, the server returns a value of 5 in the a settings:Status element, as specified in [MS-ASCMD] section 220.127.116.11.14.
