Hi Sandra,
your Outlook .pst file contains your COMPLETE outlook stuff in one file. It is a database file in a special Micrsosoft database format.

So, be carefull when sharing it: the .pst-file contains your emails, your contacts, your to-do-lists, just EVERYTHING!

Better way: create a subfolder inside your email folder, copy the emails with the pictures attached in this subfolder, use "Export" to export only this subfolder in a separate .pst file.

Then, you can transfer this to another PC. There, you have to open it in outlook by "open user file" (in German: Offnen -> Outlook-Datendatei".
