Extract Subfiles from Outlook Personal Folders Files

KeyView can extract Outlook items such as messages, appointments, contacts, tasks, notes, and journal entries from a PST file. When a PST file is extracted to disk, the body text and header information (To, From, Sent, and so on) from each Outlook item are extracted to a text file. (If you do not want the header information to appear in the text file, see Exclude Metadata from the Extracted Text File.)

You can also extract messages from PST files as MSG files, including all their attachments, using the SaveAsMSG property in the ExtractSubFileExtractConfig class.

If an Outlook item contains a non-mail attachment, the attachment is extracted in its native format to a sub directory. If an Outlook item contains an Outlook attachment, the attached item’s body text and attachment(s) are extracted to a sub directory.


The Microsoft Outlook Personal Folders (PST) reader is an advanced feature and is sold and licensed separately. To enable this reader in a KeyView SDK, you must obtain the appropriate license key from HPE.
