Gaucho100K:

I don't have problems with Outlook. My version in "about" says: Microsoft Outlook SP-3. You may check your version!?!

May be you just run an update via Internet ... like I did. And all the data, files did stay intact. BTW, you may have a copy of all your data in Palm as well?!
When I remember it correct, during the on-line-update the program asked to insert one or more office disks.
One think is a little troublesome after the update: When you send an e-mail from another program (like ACE..), Outlook asks you "is this O.K.".
