 What Gets Preserved

Everything Your Microsoft Purview Archive Contains

Every piece of information in your Microsoft Purview export is carried through to the output format without loss.

 Key Features

Built Specifically for Microsoft Purview Archive Exports

Every feature is designed around how Microsoft Purview structures its archive exports.

Per-Mailbox PST Pattern

Handles the standard Purview per-mailbox PST output where each file is named after the user email address ([email protected]). Converts each PST independently preserving all folder structure and metadata.

manifest.xml Chain-of-Custody

Reads and cross-references the manifest.xml included in every Purview export. Links each converted message to its original Microsoft 365 source location, preserving legal chain-of-custody for eDiscovery productions under FRCP Rule 34.

NonIndexedItems PST Support

Microsoft Purview creates a separate NonIndexedItems PST for messages it could not index. The converter processes this file alongside the main export so no messages are missed including encrypted attachments and corrupted messages.

Batch All-User Conversion

Load all per-mailbox PST files at once and convert the entire organisation in a single pass. One output file per user in the chosen format. No manual processing of individual PSTs required.

Results.csv Inventory Sync

Reads the Results.csv exported by Purview alongside each PST. Enriches converted output with the message-level inventory data including subject, size and source mailbox, ready for legal review platforms.

100% Offline Processing

Runs entirely on your Windows PC. Once you have the PST files from the Purview Export Tool, no internet connection is required. Your archived emails are never uploaded to any server or cloud service.

Complete Header Preservation

All email headers survive: standard headers, Microsoft 365 X-headers, exchange transport headers, anti-spam results and DKIM/SPF/DMARC authentication results. Critical for maintaining legal admissibility.

Combined PST Handling

Also handles the single-PST-for-all-mailboxes Purview export option. Identifies individual mailboxes within the combined PST and can split output per user for cleaner migration.

Preview Before Converting

Browse all mailboxes, folders and messages before committing to conversion. Verify completeness and filter by date range, sender or subject. No conversion quota consumed during preview.

Deduplication Awareness

Purview exports with deduplication enabled may merge messages from multiple folders. The converter tracks original folder paths from the PST structure so messages appear in the correct location in the output.

scanpst.exe Repair Bypass

Purview PSTs with Outlook import errors are read directly by the converter without relying on Outlook, bypassing scanpst.exe issues entirely.

Conversion Report

Generates a detailed HTML or CSV report after every conversion listing every message processed, format errors, attachment counts and any NonIndexedItems flagged. Essential for compliance documentation.

Migrating a 500-user M365 tenant produced 500 per-mailbox PSTs from Purview. The batch conversion finished overnight. manifest.xml cross-referencing meant every message retained its source mailbox metadata for the legal hold report.

Frequently Asked Questions

Common questions about converting Microsoft Purview email archive exports.

All three Purview PST output patterns: (1) One PST per mailbox named after the user email address ([email protected]); (2) One combined PST for all mailboxes; (3) Individual MSG files. The converter also processes the NonIndexedItems PST Purview generates for messages it could not index.

No. The Export key and Purview Export Tool are only needed to download the PST files from Microsoft Azure. Once the PST files are on your local machine, Univik Microsoft Purview Converter reads them directly. No Export key, no ClickOnce tool and no Microsoft connection required.

Every Microsoft Purview export includes a manifest.xml linking each exported message to its original source location in Microsoft 365. Univik Microsoft Purview Converter reads this and embeds the source location data into the converted output. For legal eDiscovery productions this preserves the chain of custody required under FRCP Rule 34.

Microsoft Purview generates a separate NonIndexedItems PST for messages it could not index — typically encrypted attachments, password-protected files and corrupted messages. Univik Microsoft Purview Converter processes this file alongside the main PST so no messages are omitted. The conversion report flags all non-indexed items for manual review.

Yes, completely offline. Once PSTs are on your local disk, all conversion runs on your Windows machine with no internet connection. Your email data is never uploaded anywhere. Critical for eDiscovery work involving privileged correspondence or HIPAA-protected data.

Yes. Convert per-mailbox PSTs from Purview to MBOX format. MBOX files import directly into Google Workspace using Google's migration tools or third-party tools like BitTitan. One MBOX per PST maps cleanly to one Google Workspace mailbox.

Yes. Univik Microsoft Purview Converter reads PST content directly without routing through Outlook's import mechanism, bypassing the conditions that cause scanpst.exe errors. Genuinely corrupted messages are identified and reported while all intact content is extracted successfully.
