2.1.3.3.16 attOwner Attribute

  • Article

The attOwner attribute is a message-level attribute that is also a meeting attribute that maps to and from the PidTagReceivedRepresenting_XXX or PidTagSentRepresenting_XXX properties, as specified in section 2.1.3.1.1.

The attOwner attribute is encoded as counted strings laid end-to-end. The format for attOwner attribute is as follows:

 attOwner=display-name-length display-name address-length address
  
 ; Length of "display-name," including terminating null character.
 display-name-length=UINT16
 display-name=*CHAR %x00
  
 ; Length of "address", including terminating null character.
 address-length=UINT16
 address= 1*CHAR ":" 1*CHAR %x00

The display-name-length and address-length are unsigned 16-bit values, including the terminating null characters for the strings. The type and address strings in the email-address entry are separated by a colon (:) character; for example, "SMTP:user1@example.com" %x00.

The mapping of message properties to the attOwner attribute is dependent on the message class of the message being encoded.
