lpszName
Pointer to the display name of the message recipient or sender.
lpszAddress
Optional pointer to the recipient or sender's address; this address is 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 not in an address book (that is, a custom recipient).
The format of an address pointed to by the lpszAddress member is [address type][e-mail address]. 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 opaque entry identifier used by a messaging system service provider to identify the message recipient. Entry identifiers have meaning only for the service provider; client applications will not be able to decipher them. The messaging system uses this member to return valid entry identifiers for all recipients or senders listed in the address book.
