None.

Child elements

Element	Description
PrincipalName	Represents the user principal name (UPN) of the account to use for impersonation. This should be the UPN for the domain where the user account exists.
SID	Represents the security descriptor definition language (SDDL) form of the security identifier (SID) for the account to use for impersonation.
PrimarySmtpAddress	Represents the primary Simple Mail Transfer Protocol (SMTP) address of the account to use for Exchange impersonation. If the primary SMTP address is supplied, it will cost an extra Active Directory directory service lookup in order to obtain the SID of the user. We recommend that you use the SID or UPN if they are available.
SmtpAddress	Represents the Simple Mail Transfer Protocol (SMTP) address of the account to use for Exchange Impersonation. If the SMTP address is supplied, it will cost an extra Active Directory lookup in order to obtain the SID of the user. We recommend that you use the SID or UPN if they are available.
