I have the same exact problem.
Either "adding" by trying to archive or just File/Open/Outlook Data File

No error message, just immediate crash.
Event viewer has just a "warning"!
ID: 6, Application Name: Microsoft Office Outlook, Application Version:
12.0.4518.1014, Microsoft Office Version: 12.0.4518.1014. This session was
terminated unexpectedly.

I did create a new profile. Same thing

How are you "adding" these PST files to your profile? What error messages do
you get?
If you attempted an in place upgrade, you should create a new profile from
scratch.

Hey there. I just upgraded to Outlook 2007 from 2003. I have several PST
files for archiving, etc. If I try to launch OL2007 with a PST in my Data
Files, OL crashes. I have disabled all add-ins, and removed all PST files.
Then OL launches ok. If I add back just one PST (even a newly created one
in
OL2007 with nothing added to it) OL crashes at launch as before. Any
ideas? I
really need to be able to use my PST files.
