When an application that can work with either Outlook or
with Exchange's MAPI tries to load an Exchange MAPI (exmapi32.dll) component
directly instead of loading a MAPI stub library on the computer, the
application does not work correctly.
For example, you run the
MfcMapi.exe tool, click
Session/Load MAPI, enter the path of
the exmapi32.dll file, and then click
Session\Logon and Display Store
Table. When you do this, you receive the following error message:
An internal MAPI error has caused this logon attempt to
fail. MAPI 1.0 [000004CA]
Currently, Mapi32 Stub Library supports multiple MAPI
components on a computer. However, in this case, some internal calls to
mapi32.dll are bypassed to the exmapi32.dll Exchange MAPI component. When the
MAPI stub is bypassed, the problem may occur because of the requests for
unexpected MAPI operations.
