I've been getting this error lately (once per day or once per session):

MAPISP32 caused an invalid page fault in module SHLWAPI.DLL

I close the error message window, and keep using the system as if nothing happened. System seems to run fine without mapisp32 (unless it's restarted again?)

Mapisp32.exe (version 5.5.3121.0) is in a strange location:

\program files\common files\system\mapi\1033\95

SHLWAPI.DLL is version 6.00.2800.1990 xpsp2.090827-1539

Is this related to using outlook 2000 and/or exchange server?

Do I need to have mapisp32 running as part of the startup group?

Well, this refers to MAPI32.DLL instead, but at least explains what the MAPI is (sort of). Also give a look at KB173299...
I think maybe you've got a version that's too new. In my machine I have MAPI32.DLL v. 4.0.410.59 and no MAPISP32.EXE at all. But I didn't install Outlook 97, because I use web-mailers, so I just have Outlook Express, updated with the Maximus-Decim packs.

I have MAPI32.DLL (version 1.0.2518.0 - comments = Service Pack 2) in the same location as Mapisp32.exe (program files\common files\system\mapi\1033\95).

The properties-description for MAPI32.DLL is: "Extended MAPI 1.0 for Windows NT". Comments: "Service Pack 3"

I also have MAPI32.DLL (version 1.0.2536.0) in \windows\system. I have no idea which one is used.

If I only do pop3 logins (no exchange server stuff) with outlook 2000, do I need MAPI / Mapisp32.exe?

Rename both MAPI32.DLL and Mapisp32.exe in program files\common files\system\mapi\1033\95 to MAPI32.ANT and Mapisp32.ANT, to disable them. Let alone \windows\system\MAPI32.DLL. Reboot and see what happens. Whatever happens, in case they are needed, all you have to do is change back their extensions. And in case you do find they are needed, try restoring just the extension of Mapisp32.ANT first, for the \windows\system\MAPI32.DLL to be used...
