Remarks

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