The PR_ORIGINAL_AUTHOR_SEARCH_KEY property is one of the address properties for the author of a message. At first submission of the message, the client application should set this property to the value of PR_SENDER_SEARCH_KEY. It is never changed when the message is forwarded or replied to.
The original author properties allow for preservation of information from outside the local messaging domain. When a message arrives from another messaging domain, such as from the Internet, these properties provide a way to ensure that original information is not lost.
For more information on the address properties, see Base Address Properties.
