There is a mismatch between the version of MAPI32.dll (something to do
with Outlook/Exchange?) and whatever program it is that you are
running. Whatever program it is that you are running was compiled
against a version of MAPI32.dll that is missing an entry point.
Typically this would mean that the program is *newer* than MAPI32.dll,
I think.
See if you have got two versions of MAPI32.dll and if you have, try to
determine which is the correct one. One not very safe way is to
temporarily rename one and reboot.
Ignore my previously post about the wrong DLL. I still think that it
is a version level, but on further reading, renaming dlls is probably
not the solution.
