Univik Zix Archive Converter

Both Zix export formats: (1) PST — one PST file covering the exported messages, suitable for direct Outlook import; (2) EML + ZIP — individual EML files in a ZIP archive, one file per message. The converter also reads the metadata_inventory.csv file included in every Zix export, which records date, sender, recipient, subject and original encryption status (plain, Zix Encrypted, TLS Secured) for every exported message.

Yes — this is the most common Zix conversion request. Outlook cannot import EML files natively. Univik Zix Archive Converter converts the Zix EML+ZIP archive to a fully importable PST file with all messages, attachments, headers and metadata preserved. No Outlook installation required on the conversion machine. The converted PST imports directly into Outlook or via the Microsoft 365 Import Service.

Every Zix export includes a metadata_inventory.csv listing every exported message with its date, sender, recipient, subject, original encryption type (plain, Zix Encrypted, TLS Secured) and file size. Univik Zix Archive Converter reads this file and: (1) validates that every message in the inventory is present in the converted output, flagging any discrepancies; (2) embeds the original encryption status in the converted output for audit trail purposes. The encryption status field is particularly important for HIPAA and GDPR compliance productions where the handling of encrypted messages must be documented.

Yes. Convert the Zix PST to MBOX format using the converter. The MBOX output imports directly into Google Workspace using Google's migration tools or third-party tools such as BitTitan or AvePoint. The original Zix encryption status from the metadata_inventory.csv is preserved in MBOX X-headers for audit continuity in the destination mailbox.

Yes, completely offline. Once you have downloaded the export files from the Zix portal, all conversion runs locally on your Windows machine. No Zix portal login, no OpenText connection and no internet access is required. This is particularly important for healthcare organisations converting HIPAA-protected archives — previously encrypted content stays entirely within the local environment.

Minimal requirements:

• RAM: 4 GB minimum (8 GB recommended for large EML+ZIP archives)
• Disk: 50 MB installation plus space for output files

Yes. Univik Zix Archive Converter handles PST and EML exports produced by Zix Message Archiving under both the original Zix Corporation branding and the current OpenText ownership. The export format and metadata_inventory.csv structure have not changed with the acquisition. If you are accessing through an OpenText portal labelled as Message Archiving or Email Archiving, the converter processes the output identically.
