Hello: I had the same issue. After reading this thread, I started to uninstall the Office 2003 updates (fixes) one by one and uninstalling/reinstalling olconn2, until things worked. Then I went to Microsoft Update and reinstalled all the updates, and things still work. I did not have the KB fix numbers referred to here, but I think those fixes change numbering every so often, depending on the dates of the update. So my suggestion is to do what I describe here as it should work. What I gather from this is that there seems to be some incompatibility between olconn2 and some Microsoft updates, but that you should be OK if you get olconn2 to work before installing such updates.
