Outlook can open any PST file from any version. In no way would it expect
any other file type. Might want to tell us what you are doing instead of
opening a PST file.

Looking through the correspondence on other related issues I note Brian
Tillman reiterating that you should never import/export. It is easy to
copy
entries between .pst files without importing/exporting, and I only tried
it
in the current situation in desperation to get something to unstick. The
real issue is that I can't open a 2000 .pst file using Outlook 2007
because
it is expecting a .ics or .vcs file. The guidance is to create a "new"
.pst
file amnd "move" the old entries into it. Any suggestions?

I want to import an Outlook 2000 .pst calendar into a new .pst format so
it
can be opened by Outlook 2007. I am following the instructions on the
Office
Help page "Convert a non-Unicode data file (.pst) to a Unicode data file
(.pst)". When I try to create a new data file I get the message "There
was
an error locating one of the items needed to complete this operation. It
might have been deleted". When I try to import items to the new data

get the message "The operation failed. An object cannot be found". There

no guidance on the web page as to what to do in these circumstances. Do
I
need to install additional files from the Office 2007 disc?
