Quick Info

Header file: MAPISPI.H
Exposed by: Message store logon objects
Implemented by: Message store providers
Called by: MAPI
Interface identifier: IID_IMSLogon
Pointer type: LPMSLOGON

Vtable Order

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

OpenEntry Opens a folder or message object and returns a pointer to the object to provide further access.
CompareEntryIDs Compares two entry identifiers to determine if they refer to the same 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.
