Search multiple .pst files at once

This article explains how to search multiple .pst files without Outlook at once. Any .pst file (archive, password protected or encrypted) can be searched together with any others. This means that if you're searching for a sensitive email, private contact or calendar item, but you're not certain which file or account you put it in, you'll be able to find it easily with a single search.
