When you retire Archive Manager, the exports you pull from Enterprise Manager become the record that matters. This Windows desktop tool reads those PST and EML files, journal mailboxes and AM export logs included, checks them for completeness and converts everything into MBOX, MSG, PDF or any of 10+ open formats you can keep for good.
*The trial converts 25 emails from each Archive Manager export so you can check the output first. A license removes the cap.

Inside the Export
Whatever Archive Manager wrote into the export comes out the other side: headers, addresses, dates, attachments and flags exactly as archived.
Feature Set
Everything here assumes an Archive Manager export, because that is exactly what the tool was built around.
Stub and Archive Body Handling
Quest Archive Manager stubs archived messages in Exchange mailboxes. An export run from Enterprise Manager retrieves full content from the Quest storage database, while a plain Exchange mailbox export copies only the stubs. This converter reads both correctly and never mistakes an AM stub for the full message content behind it.
Journal Mailbox Coverage
A journal archive built by Archive Manager wraps each message in an envelope that names every BCC recipient and every SMTP hop. That wrapper travels into the converted output untouched, ready for SEC, FINRA and CFTC productions that turn on routing evidence.
Export Log Cross-Reference
Quest Archive Manager generates an export log alongside every PST job. The converter reads this log and cross-references it against the converted output to identify any messages present in the log but absent from the output. Completeness verified before migration.
Whole-Export Batch Runs
Load all per-mailbox PST exports from Quest Archive Manager at once. Converts the entire organisation in a single pass outputting one file per mailbox. Designed for mid-market Exchange organisations with 50 to 500 mailboxes migrating to Microsoft 365.
Original Folder Structure
Recreates the complete Exchange folder hierarchy from the Quest AM PST export. Inbox, Sent Items, Deleted Items and all custom folder names preserved. Users find archived emails in the correct Outlook folders after migration to M365 or Google Workspace.
Fully Offline Operation
Once the PST files are exported from Quest Archive Manager and copied to local disk, no Quest AM server, Quest software or network connection is required. All conversion runs locally on your Windows machine.
Headers Carried Whole
All email headers survive: RFC 5322 standard headers, Quest AM X-headers, Exchange transport headers and SPF/DKIM/DMARC results. Critical for maintaining legal admissibility of Quest Archive Manager-archived evidence.
Look Before You Convert
Browse all mailboxes, folders and messages before conversion. Verify folder structure and message counts. Apply date range, sender or subject filters. No conversion quota consumed during preview.
Repair Broken PSTs
Some Archive Manager PSTs carry structural quirks that make Outlook refuse the import. The converter never asks Outlook: it parses the PST itself, sidesteps scanpst.exe entirely and pulls out everything readable.
Quest AM EML Export Support
Also handles EML exports produced by Quest Archive Manager's message-level export feature. Loads EML files or folders of EML files, preserving all Quest AM-added metadata and X-headers, then converts to PST, MBOX, PDF or any other format.
The Run Report
Generates a detailed report listing messages processed per mailbox, export log match status, journal envelope summary and any conversion errors. Essential documentation for Quest Archive Manager decommissioning projects.
No Quest Software Required
No Quest Archive Manager client, Quest Management Shell or Quest Software installation needed on the conversion machine. Reads Quest AM PST and EML export files as standalone files, deployable on any Windows PC.
Fidelity
Every header, address, date and flag arrives in the new format exactly as the archive stored it.
The Workflow
A four-step run you can finish the same afternoon you export.
Export from Quest Archive Manager
In Enterprise Manager, run an Advanced Search on the target mailboxes or journal archives, choose Export Data with Folder Hierarchy selected and let the export task write the PST files.
Collect the PST Files
Copy the per-mailbox PST files and the Quest AM export log from the output folder to your local machine.
Load into Converter
Open Univik Quest Archive Manager Converter, click Add Files or Add Folder and select all PST or EML files plus the export log. The converter detects journal archives automatically.
Choose Format and Convert
Select MBOX, EML, PDF, MSG or any of 10+ output formats. Click Convert. Journal envelope data and folder structure are preserved in the output.

Reasons to Leave
Where this converter earns its keep in real Exchange environments.
Stub and Full Content Aware
Reads Quest AM exports as they really are: stubs and full messages told apart reliably. Run the export from Enterprise Manager rather than the Exchange mailbox to include the archived bodies.
Envelope Wrapper Intact
The envelope wrapper around each journaled message, BCC list and SMTP trail included, survives conversion for SEC and FINRA productions.
Export Log Validation
Reads the Quest AM export log and validates completeness. Zero-loss confirmed before decommissioning.
Local & Private
No Quest AM server after export. Runs standalone on any Windows machine.
Repairs Broken PSTs
Reads Quest AM PSTs that fail scanpst.exe. Extracts all recoverable content.
Cloud Import Ready
PST imports via M365 Import Service. MBOX imports into Google Workspace. Standard Quest AM migration path.
Destinations
Outlook and M365 accept the PST, Google Workspace takes the MBOX and your compliance reviewers get their PDF with the envelope intact.

Who Runs This
The people who run this are usually the same people who ran the archive.
MSPs & System Integrators
Mid-market Exchange organisations migrating off Quest Archive Manager to Microsoft 365. Batch convert all mailbox PSTs with journal envelope and export log validation.
eDiscovery Professionals
Converting Quest AM exports for legal review platforms. Journal envelope BCC data and SMTP routing preserved for FRCP and SEC productions.
Legal & Compliance Teams
Producing PDF archives from Quest AM exports for SOX, HIPAA or FRCP retention. Export log integration provides completeness documentation.
IT Administrators
IT admins decommissioning Quest Archive Manager. Convert multi-year PST archives offline without Quest AM server active.
Digital Forensics Analysts
Forensic investigators working with Quest AM evidence exports. Offline conversion with full Exchange header chain intact.
Compliance Officers
Converting Quest AM journal archives for long-term PDF storage. Journal envelope BCC data preserved for SEC Rule 17a-4 and FINRA retention.
Field Reports
What Exchange admins and compliance teams told us after their Archive Manager projects.
Decommissioning Quest Archive Manager across 350 Exchange mailboxes. The converter handled journal archives and per-mailbox PSTs in one batch. Export log cross-reference confirmed 100% completeness before we shut down the Quest AM server.
We had Quest AM journal archives needed for an SEC inquiry. Journal envelope BCC data and SMTP routing preserved in PDF output. Legal counsel accepted the production without supplementation on chain-of-custody grounds.
Two Quest AM PSTs from a legacy storage array had scanpst.exe errors. Univik read both directly, extracted every message and produced clean MBOX output. The export log showed they were complete despite the structural errors.

A Different Kind of Exit
Leaving a Product That Is Not Dead
Archive Manager is alive and supported by Quest. Teams retire it anyway, for reasons that have nothing to do with end of life.
The tenant moved
Once mail lives in Microsoft 365 with its own archiving and retention, running a separate archive server next to it stops making sense.
Per-mailbox licensing
An archive licensed by mailbox count keeps costing money for mail nobody sends anymore. A one-time conversion ends that line item.
Stub friction
Opening archived mail from Outlook needs the plug-in and registry settings on every machine. Each Outlook and Windows refresh renegotiates that setup.
One archive too many
Mergers leave companies running two or three archive products. The smallest one usually gets converted out first.
None of these need a rescue project. Export the mailboxes from Enterprise Manager while the system is healthy and convert on your own schedule. That is the calmest migration there is.
From the Quest Knowledge Base
Export Numbers Worth Knowing
Quest's own documentation carries a few defaults that shape what your export looks like before the converter ever sees it.
2 GB is the default split
Enterprise Manager breaks export PSTs into 2 GB parts unless you change the export task properties. Quest suggests staying under 20 GB per file since oversized PSTs corrupt easily. Either way the converter takes the whole numbered set as one batch.
10,000 items is the search cap
A mailbox export built from search results returns 10,000 items by default. Bigger mailboxes need that limit raised in Settings or the export split by date range. Otherwise mail silently stays behind. Count your items before trusting an export.
Bulk runs have their own tool
For many mailboxes at once, Quest provides the CSVtoXML utility to generate export tasks in bulk instead of clicking through each mailbox. Exports land in the MAM4Exchange Export folder by default, ready for conversion.
Questions
Answers for the questions that come up mid-project.
The PST was exported from the Exchange mailbox instead of from the archive. Archive Manager replaces archived messages in Exchange with shortcut stubs that point to the archive store, so a mailbox-level export copies the stubs. Export from Archive Manager itself instead: open Enterprise Manager, run an Advanced Search on the mailbox and choose Export Data. That export writes the full messages from the archive.
Yes. An Archive Manager journal mailbox keeps each message inside its envelope wrapper, the layer that records BCC recipients and the SMTP routing trail. The converter carries that wrapper into every output format, which regulators expect for productions under SEC Rule 17a-4, CFTC and FINRA where routing must be documented.
Quest Archive Manager generates an export log file alongside every PST export listing every message exported and any items skipped. The converter reads this log and cross-references it with the converted output to identify any gaps before migration. The final conversion report shows which log items were converted and which were flagged as missing. Essential for compliance documentation during Quest AM decommissioning.
No. Once the PST or EML files are on local disk, no Quest Archive Manager client, Quest Management Shell, Quest Software framework or any other Quest infrastructure is required. Conversion runs completely offline on a standalone Windows PC.
Yes. Convert per-mailbox Quest AM PSTs to MBOX. MBOX output imports directly into Google Workspace using Google's migration tools or BitTitan. Journal envelope data is preserved in MBOX X-headers for compliance continuity in Google Workspace.
Yes. Quest AM PSTs with scanpst.exe errors are read directly by the converter, bypassing Outlook's import mechanism. All recoverable content is extracted and corrupted items are flagged in the conversion report.
It runs on Windows 7 through Windows 11 with 4 GB of RAM, though 8 GB is more comfortable for large archives. Installation takes about 50 MB plus room for your output files and it needs .NET Framework 4.8 or higher, already present on updated Windows 10 and 11.
Free trial converts the first 25 messages per archive. All features fully functional including journal envelope handling, export log reading, all 10+ output formats and preview. No time limit.
Open Enterprise Manager, the Archive Manager Administration Center. Click Advanced Search on the toolbar, select the target mailbox and leave the criteria blank to return every archived item. Right click a result, choose Export Data and keep Folder Hierarchy selected so the PST mirrors the mailbox. The PSTs land in the export folder, by default under Program Files (x86)\Metalogix\MAM4Exchange\Export. For very large mailboxes, raise the item limit in Settings or split the search by date range. ArchiveWeb offers the same export for keyword searches.
Quest Archive Manager, also sold as Metalogix Archive Manager for Exchange, is a mature mid-market product. Quest Software continues to maintain it but new enterprise sales increasingly favour cloud-native archiving. Many Quest AM customers are in active migration projects moving to Microsoft 365 Purview Compliance or Google Vault. Univik Quest Archive Manager Converter is specifically designed for these legacy migration scenarios.
Archive Manager splits export PSTs at 2 GB by default. The limit can be raised in Tools then Export Tasks inside Enterprise Manager and Quest recommends keeping PST files under 20 GB. The converter loads all the parts of a mailbox together, so the split makes no difference to the output.
Quest Archive Manager is an email archiving product for Exchange, known for years as Metalogix Archive Manager. It moves mailbox messages into a central archive and leaves shortcut stubs behind, all administered through its Enterprise Manager console. Companies retiring the platform export mailboxes to PST or EML and convert those exports to open formats.
A migration service connects to the running Archive Manager environment and moves everything to a new platform end to end, usually priced per mailbox. This converter fits the simpler case: the environment is being retired anyway and exports exist or can be produced from Enterprise Manager. One license covers the conversion instead of a project budget.
