PR_ENTRYID 

The PR_ENTRYID property contains a MAPI entry identifier used to open and edit properties of a particular MAPI object.

Quick Info

Remarks

The PR_ENTRYID property identifies an object for OpenEntry to instantiate and provides access to all of its properties through the appropriate derived interface of IMAPIProp.

PR_ENTRYID is one of the base address properties for all messaging users. For more information on the base address properties, see Base Address PropertiesN3YFFO.

PR_ENTRYID can contain either a long-term or a short-term identifier. Short-term identifiers are easier and faster to construct, but are limited in their scope and duration, typically to the current session and workstation. They are commonly used for objects of a temporary nature, such as table rows or dialog box entries, and then abandoned. Long-term identifiers are used for objects of a more wide-ranging and long-lasting nature.

PR_ENTRYID is always available through the IMAPIProp::GetPropsK06IXU method following the first call to the IMAPIProp::SaveChanges21IFXQ method. Some service providers can make it available immediately after instantiation. The provider must always return a long-term entry identifier from GetProps. Therefore, to convert a short-term identifier to long-term, simply open the object and get its PR_ENTRYID through GetProps.

The following table summarizes important differences among PR_ENTRYID, PR_RECORD_KEYQV4J.N, and PR_SEARCH_KEY_7GFC6.
