If you don't have a valid Intella license, you can get a free 14-day trial version from Vound Software's website (check the See also section). You will also need a PST or OST file to follow this recipe. It's easy to get one: simply use your own email address with Outlook, then go to C:Users\%USERNAME%AppDataLocalMicrosoftOutlook and get your file. This will be your evidence source, in our case an OST file.
PST files are used for POP3, IMAP, and web-based mail accounts, while OST files are used when a user has an Exchange account and wants to work offline.
