Is there a way to Compact Outlook .pst files without opening them in Outlook?

Question

When you delete information from an Outlook Personal Folder File (.pst) the file size does not decrease until you open the properties of that Personal Folder in Outlook, click Advanced and then click Compact Now. I would like to do this for multiple .pst files in multiple locations without having to open them in My Outlook. Is there a Microsoft Utility that can do this, and more specifically is there one that can be accessed by the command line so that I can script this process out.

Answer 1

I think SCANPST.exe does the compaction when you run it for a file. Although I have never tried it for that purpose.
