Aside from the fact that you provided no info regarding versions of either
product - this is not an Outlook question but rather a Photoshop Organizer
issue (it's not Outlook that is having a problem)
You may want to start with the link below as a starting point and if it
doesn't address your problem - follow up with a question to Adobe support
http://kb.adobe.com/selfservice/viewContent.do?externalId=kb402712
(hint: at a minimum you need to find out what version(s) of Outlook that
Photoshop Org supports versus the Outlook version you are using)
As for not being able to "open" a PST file - not sure what you're expecting
since a PST file is a proprietary Outlook file so being bumped to the main
Outlook screen is exactly what should be happening - the same way that
clicking on an .XLS file type will launch MS Excel.
