3.1.4.1.5 Setting a Recipient Flag
The client sets the following properties to flag a Draft Message object with a recipient flag. When a recipient flag arrives in the recipient's mailbox, it appears as a basic flag.
PidTagFlagStatus (section 2.2.1.1)
PidTagReplyRequested (section 2.2.1.4)
PidTagResponseRequested (section 2.2.1.5)
PidLidFlagRequest (section 2.2.1.9)
PidLidFlagString (section 2.2.1.10)

PidLidTaskComplete (section 2.2.2.2)
PidLidTaskStatus (section 2.2.2.1)
PidLidPercentComplete (section 2.2.2.3)
If the client supports sender flags, the PidTagSwappedToDoStore property (section 2.2.1.8) is set to trigger the post-transmit processing specified in section 3.1.4.3.
