Vtable Order

GetLastError	Returns a MAPIERROR structure containing information about the last error that occurred for the message store object.

Remarks

The message store logon object is the part of an open message store provider that is called directly by MAPI. There is a one-to-one correspondence between the message store logon object called by MAPI and the message store object called by client applications; you can think of the logon and store objects as one object exposing two interfaces. The two objects are created together and freed together.
