MAPI Properties

MAPI Property: PR_REPLY_RECIPIENT_NAMES, PR_REPLY_RECIPIENT_NAMES_A, PR_REPLY_RECIPIENT_NAMES_W
Description: Contains a list of display names for recipients that are to get a reply.
Property ID: $0050
Property type: PT_STRING8, PT_UNICODE
Area: MAPI envelope
Remarks:
 These properties contain the display names separated by semicolons.

When this property is not present, a reply is sent only to the user identified by the PR_SENDER_NAME (PidTagSenderName) property. When PR_REPLY_RECIPIENT_ENTRIES (PidTagReplyRecipientEntries) and these properties are defined, the reply is sent to all of the recipients identified by these two properties. A transport provider uses these properties to override the usual reply logic.

If either PR_REPLY_RECIPIENT_ENTRIES or these properties are set, the other property must be set also. These properties must contain the same number of recipients, and they must contain them in the same order. Failure to observe these requirements can cause unpredictable results.
