Abel, I posted the info below in another post while looking for any answers
to similar problems you describe...here is what I found:

We are having problems using the "Outlook 2003/2002 Add-in: Notes Connector"
(download file olconn2.exe on Microsoft's download site.) We have been using
this successfully...with a few minor "annoyances," however, recently things
went haywire. I spent time yesterday and found this - it seems to be
associated with Office 2003 SP2...if the connector was already loaded and the
upgrade was done, things worked but started getting duplication problems,
etc...if SP2 was loaded prior to the connector load and setup, we could not
even get it fuctioning at all...the .nst file would create but could not be
read properly after that (file not available error.)

I took a workstation we were having the problem with, uninstalled office,
reloaded with Office SP1 and any updates prior to SP2, everything works fine.

There seems to be a problem with the current available connector
(olconn2.exe dated 4/12/2004 and Office 2003 SP2. There doesn't seem to be a
newer connector available and I do not know yet if there are any plans to fix
this issue either with a fix to Office SP2 or a new connector.

If anybody knows anything, please respond.

Thanks
