primary SMTP address and other proxy addresses are typically set by email address policies.Valid syntax for this parameter is [<Type>]:<emailaddress1>,[<Type>]:<emailaddress2>…. The optional <Type>
value specifies the type of email address. Some examples of valid values include:
If you don’t include a <Type> value for an email address, the value smtp is assumed.
