MapiRecipDescW structure (mapi.h)

A MapiRecipDescW structure contains information about a message sender or recipient.

Syntax

typedef struct {
  ULONG ulReserved;
  ULONG ulRecipClass;
  PWSTR lpszName;
  PWSTR lpszAddress;
  ULONG ulEIDSize;
  PVOID lpEntryID;
} MapiRecipDescW, *lpMapiRecipDescW;

Members

ulReserved

Reserved; must be zero.

ulRecipClass

Contains a numeric value that indicates the type of recipient. The following values are possible.

Value	Meaning
MAPI_ORIG 0	Indicates the original sender of the message.
MAPI_TO 1	Indicates a primary recipient of the message.
MAPI_CC 2	Indicates the recipient of a copy of the message.
MAPI_BCC 3	Indicates the recipient of a blind copy of the message.

lpszName

Pointer to the display name of the message recipient or sender.

lpszAddress

Optional pointer to the recipient or sender's address. This address contains provider-specific message delivery data.

Generally, the messaging system provides such addresses for inbound messages. For outbound messages, the lpszAddress member can point to an address entered by the user for a recipient that is not in an address book (a custom recipient).

The format of the address is address type:email address. Two examples of valid addresses are FAX:206-555-1212 and SMTP:M@X.COM.

ulEIDSize

The size, in bytes, of the entry identifier pointed to by the lpEntryID member.

lpEntryID

Pointer to an entry identifier that cannot be deciphered by client applications and that is used by a messaging system service provider to identify the message recipient.

These entry identifiers have meaning only for the service provider. The messaging system uses this member to return valid entry identifiers for all recipients or senders listed in the address book.
