PST Email Address Extractor Tool for Bulk Contact Extraction

No. The current PST Email Address Extractor reads PST mailbox data directly, so Microsoft Outlook does not need to be installed or configured on the computer. It scans the PST file and saves separate CSV, TXT, HTML, or other supported output.

The PST Email Address Extractor works with PST files generated by Outlook for Microsoft 365 and every major standalone release, including Outlook 2021, 2019, 2016, 2013, 2010, and 2007. This broad compatibility lets you pull addresses from virtually any PST archive-regardless of the Outlook version that created it.

Install the SysCurve PST Email Address Extractor, launch it, and click Add File to load PST archives. Select your preferred export format-CSV, JSON, XML, VCF, HTML, or TXT-choose a destination folder, and press Export. The program scans each message, removes duplicate addresses, and writes a clean contact list in the format you specified. Outlook must be present, but the workflow takes only a few clicks and no advanced configuration.

No. The Outlook PST email extractor works in strict read-only mode, so it never writes back to the source file or alters message headers. All processing happens in memory, and only the extracted addresses are saved to your chosen output directory. This design preserves the integrity of your PST archive for compliance audits and future reference, ensuring zero risk of data corruption or accidental changes.
