Key Features
Built specifically for Proofpoint Archive export jobs — handles EDRM XML, Relativity load files, EML ZIP exports and the 100K message per-job limit that generic converters cannot stitch back together.
Multi-Job Export Merging
Proofpoint limits each search export to 100,000 messages. Large archives require multiple export jobs with refined search parameters. The converter loads all jobs in one session and stitches them into a single chronological PST, MBOX or PDF output — no manual merging required.
Multi-Custodian Export Processing
Proofpoint exports can contain messages from multiple custodians in a single export job. The converter separates output by custodian email address, producing one PST, MBOX or PDF file per user — matching the per-custodian structure required by Relativity, Nuix and other legal review platforms.
Outlook PST Output
Convert Proofpoint EML ZIP or PST export jobs to fully importable Outlook PST files. Proofpoint PST exports sometimes have structural differences from standard Outlook PSTs — the converter normalises these for clean import into any Outlook version or Microsoft 365.
Complete Attachment Preservation
Every attachment in Proofpoint archived emails is preserved — documents, images, PDFs, spreadsheets and archives. Inline images and embedded content transfer intact to all output formats.
EDRM XML Metadata Preservation
Proofpoint Enterprise Archive exports an EDRM (Electronic Discovery Reference Model) XML file alongside MSG or EML content. This XML links each message to its archive record, custodian and retention metadata. The converter reads and preserves EDRM XML linkage in the converted output — required for legal admissibility under FRCP Rule 26.
Export Job & Case-Aligned Filtering
Proofpoint lets you assign exports to a named case. The converter lets you filter conversion by Proofpoint case name, custodian or date range — converting only the messages that match your eDiscovery matter scope without reprocessing unrelated export jobs.
Relativity Load File Support
Proofpoint Enterprise Archive can export Relativity-formatted MSG or EML files with an accompanying Relativity load file (.DAT or .OPT). The converter reads this load file structure and converts Proofpoint Relativity exports to standard PST, MBOX or PDF — making data accessible outside the Relativity environment without re-tagging.
100% Offline Processing
No internet required. Proofpoint Archive export jobs containing privileged legal correspondence, healthcare data under HIPAA or financial records under SOX are converted entirely locally on your Windows PC. No data is re-uploaded to Proofpoint or any other server during or after conversion.
Export Job Preview & Deduplication
Browse all emails loaded across multiple Proofpoint export jobs before converting. The preview identifies duplicate messages that appear across multiple jobs — common when export date ranges overlap — and deduplicates by Message-ID before the final output is written.
Per-User Output Organisation
Proofpoint export jobs can contain emails from many custodians. The converter automatically separates output by custodian email address, creating one PST, MBOX or PDF file per user. Or merge all users into a single archive — choose the output structure that fits your workflow.
JSON & CSV Export Conversion
Proofpoint Enterprise Archive exports data as JSON or CSV in addition to MSG/EML formats. The converter reads Proofpoint JSON export jobs and converts them to standard email formats (EML, MBOX, PST) or readable document formats (PDF, HTML) — making JSON-exported archive data accessible without custom parsing.
Export Size Estimation Alignment
Proofpoint estimates export size before you confirm. The converter reports match Proofpoint’s pre-export item and size estimates, letting you verify the converted output accounts for exactly the same message count that Proofpoint reported — flagging any discrepancy for investigation before the archive is handed to legal counsel.
Everything Preserved from Proofpoint Archive During Conversion
Simple Process
No technical knowledge required. Load your Proofpoint export job, choose a format and convert in minutes.
Load Proofpoint Export Job
Click "Add ZIP" to load your Proofpoint export job ZIP, or "Add PST" for PST exports. Add multiple export jobs at once — the converter deduplicates and merges them automatically.
Preview & Deduplicate
Browse all emails across loaded export jobs. The deduplication check identifies messages that appear in multiple jobs due to overlapping date ranges. Apply custodian, case or date filters to narrow the conversion scope.
Select Format
Choose PST for Outlook, MBOX for Thunderbird, PDF for compliance review, MSG for individual messages, EML or any of 10+ formats. EDRM metadata is embedded in the output.
Convert & Verify Output
Click "Convert". Output files are written per custodian. A post-conversion report shows message counts per export job, deduplication statistics and EDRM metadata preservation status for verification against Proofpoint’s pre-export estimates.

Proofpoint EML ZIP exports cannot be opened in Outlook and EDRM or Relativity exports are only readable inside legal review platforms. A dedicated converter makes Proofpoint archive data accessible and portable.
Platform Migration
Moving from Proofpoint to Microsoft 365 Purview, Google Vault or another archiving platform? Export all archive data as PST or EML and convert to the format required by your new platform before the Proofpoint subscription ends.
✓ Full archive portability
eDiscovery Outside Relativity
Legal teams working outside the Relativity platform need Proofpoint Relativity exports converted to PST or PDF. The converter reads Relativity load files and produces standard output with EDRM metadata preserved for use in any litigation support system.
✓ Platform-independent output
Microsoft 365 / Outlook Access
Proofpoint EML ZIP and EDRM exports cannot be opened in Outlook. Converting to PST lets users access their complete Proofpoint archive in Microsoft 365 or Outlook — including historical emails archived before an Office 365 migration.
✓ Direct Outlook import
Subscription Expiry Protection
Proofpoint archived data becomes inaccessible when a subscription lapses. Export and convert all archive data to PST, MBOX or PDF before your contract ends — creating permanent, application-independent offline copies that remain readable without any Proofpoint dependency.
✓ Permanent offline copies
Digital Forensics
Investigators processing Proofpoint export jobs as evidence need EDRM XML metadata preserved for chain-of-custody verification. The converter maintains the EDRM linkage from archive record to exported message in the converted output.
✓ EDRM chain of custody
100K Message Limit Workaround
Proofpoint limits each export to 100,000 messages. Large archives require multiple export jobs. The converter automatically merges all jobs into one unified output file — solving the fragmentation problem that makes large Proofpoint archive migrations so time-consuming manually.
✓ Unlimited archive size
Export Formats
Choose the output format for your destination — Outlook migration, litigation platform, compliance archiving or long-term offline storage. EDRM metadata is embedded wherever applicable.

Customer Reviews
Verified reviews from eDiscovery professionals, IT administrators and legal teams who converted their Proofpoint Archive export jobs.
We had 14 separate Proofpoint export jobs from a case that exceeded the 100K message limit. Every other tool treated them as separate archives. This was the only converter that merged all 14 jobs, deduplicated the overlapping date ranges and produced a single per-custodian PST set ready for Relativity import.
We were migrating from Proofpoint to Microsoft Purview and needed all archive data as PST before the subscription expired. The converter handled our EDRM and EML ZIP exports in one session and matched Proofpoint’s pre-export item count exactly — confirmed zero message loss.
We produced Proofpoint Relativity exports for opposing counsel but they couldn’t open them outside Relativity. Converting to PDF with EDRM metadata intact gave counsel a fully admissible, platform-independent production. The EDRM chain of custody was preserved exactly as Proofpoint reported.

Common questions about converting Proofpoint Archive export jobs.
Proofpoint Archive exports data in five formats: (1) PST — Microsoft Outlook format, (2) Relativity MSG/EML — formatted specifically for the Relativity review platform with a load file, (3) EDRM MSG/EML — Electronic Discovery Reference Model format with an XML metadata file, (4) CSV — metadata spreadsheet, and (5) JSON — structured data format. Proofpoint Essentials exports a ZIP file containing EML files. Univik Proofpoint Archive Converter handles all five enterprise formats and the Essentials EML ZIP.
EDRM (Electronic Discovery Reference Model) is an industry standard for exchanging eDiscovery data between platforms. When Proofpoint Enterprise Archive exports in EDRM format, it produces an XML file alongside MSG or EML content files. The XML links each message to its archive metadata, custodian and retention information — providing a verifiable chain of custody required under FRCP Rule 26. Univik Proofpoint Archive Converter reads the EDRM XML automatically, preserving these links in the converted output so the chain of custody remains intact in PST, MBOX or PDF format.
Yes, completely offline after the Proofpoint export download. Once you have downloaded your export job ZIP or PST files from Proofpoint, all conversion runs locally on your Windows PC with no internet connection needed. Your archive data — including privileged legal correspondence, HIPAA-protected healthcare communications and SOX-regulated financial records — is never re-uploaded to Proofpoint or any other server. This is essential for maintaining attorney-client privilege and satisfying data handling requirements in regulated industries.
Proofpoint limits each search export to 100,000 messages. For archives larger than this, you must create multiple export jobs using narrowed search parameters (e.g., by date range, custodian or search terms). Univik Proofpoint Archive Converter solves the fragmentation problem — load all export job ZIPs in one session and the converter deduplicates messages that appear in multiple jobs (common when date ranges overlap) and stitches all jobs into a single unified PST, MBOX or PDF output per custodian. No manual counting or merging required.
Yes. Proofpoint Enterprise Archive exports Relativity-formatted MSG or EML files with an accompanying .DAT or .OPT load file specifically structured for the Relativity review platform. Univik Proofpoint Archive Converter reads the Relativity load file, maps the metadata fields and converts the content to PST, MBOX or PDF — making Proofpoint Relativity exports accessible outside the Relativity environment without requiring a Relativity licence or re-tagging from scratch.
Follow these steps for Proofpoint Archive: (1) Log into Proofpoint Archive, (2) Run a search using the Search sidebar, (3) Click the Export icon above search results, (4) Name the export job and enter an optional password, (5) Select the format — PST, Relativity MSG/EML, EDRM MSG/EML, CSV or JSON, (6) Optionally assign the export to a case and share with colleagues, (7) Click Export — Proofpoint shows an estimated item count and file size before confirming, (8) Download the export job ZIP when complete, (9) Load into Univik Proofpoint Archive Converter and convert. Note: Exports are limited to 100K messages per job. Create multiple jobs with narrowed search parameters for larger archives. Only Discovery Users have export access by default.
Yes, 100% attachment preservation. Every attachment in Proofpoint archived emails is preserved during conversion: documents (Word, Excel, PDF), images (JPEG, PNG, GIF), archives (ZIP, RAR) and inline embedded content. Proofpoint fully stores attachments in its cloud archive — there is no stubbing mechanism as found in on-premises archivers. All attachment types remain fully accessible in PST, MBOX and PDF output.
