When the MAPI PR_ENTRYID property is requested on a contents table, a short-term MAPI entry identifier is returned. The usual way to recover the long-term entry identifier for an object such as a message is to use the MAPI OpenEntry function to open the object and the IMAPIProp::GetProps method to read the PR_ENTRYID property from the object itself. However, the Microsoft Exchange Server information store allows users to obtain long-term entry identifiers directly from contents tables through the PR_LONGTERM_ENTRYID_FROM_TABLE property.
For more information on the PR_ENTRYID property and the OpenEntry function, see the MAPI Programmer's Reference.
