Key Features
Built for IT administrators and system managers migrating away from QNAP Xeams or archiving historical mailboxes.
Once the Xeams message folders are copied off the QNAP using File Station, an SMB share or the Container Station volume, Univik Converter works entirely on your local Windows machine. No VPN, no NAS IP, no QTS login. This makes conversion practical when decommissioning a NAS, restoring from backup or working from a different site.
Xeams organises messages by repository (Good, Possible Spam, Junk) and per-user IMAP mailboxes with Inbox, Sent, Drafts and custom folders. Univik Converter reads the full folder hierarchy and recreates it in the output. PST output mirrors the structure as Outlook folders. EML output creates matching directories. No emails are ever merged or flattened.
Point Univik Converter at the Xeams repository folder and run it once. Every user mailbox and the global archive is processed in sequence and generates its own output file named after the mailbox. For organisations with 50 or 500 users, this eliminates the manual effort of converting one mailbox at a time.
All file attachments are extracted from the Xeams message files and embedded in the output. Email metadata including From, To, CC, BCC, Subject, Date, Message-ID and all RFC 5322 headers are preserved exactly as stored. No attachment is lost and no header is stripped during conversion.
Convert only emails within a specific date range, from specific folders or matching a subject keyword. Filters let you extract only the legally required emails for a compliance request or only the last six months of a departing employee's inbox rather than their entire seven-year email history.
Business email archives contain highly sensitive communications. Univik Converter processes every Xeams message file locally on your Windows machine. No emails are transmitted to any server, no cloud processing occurs and no internet connection is required. The conversion log records every file processed for internal audit purposes.

How It Works
Copy the data off the NAS, convert on Windows, import into your destination system.
On the QNAP, locate the Xeams data directory containing the Good email repository and the UserRepository mailboxes. Copy these folders to a Windows PC via File Station, an SMB share or the Container Station volume. Keep the folder structure intact for accurate mailbox identification.
Xeams stores each message as an individual RFC822 file inside date-named folders.
Open Univik Xeams Converter. Browse to a single mailbox folder or the full Xeams repository for batch processing. Preview shows message counts, folder structure and date ranges for each mailbox. Apply any date or folder filters needed before conversion.
Select output format and destination folder. Click Convert. Each mailbox generates its own output file. Import PST files directly into Outlook or Microsoft 365. Move EML files into Thunderbird or any IMAP server. Send PDF archives to your compliance storage.
Use Cases
The organisations and IT teams that rely on Univik Xeams Converter.
When a QNAP NAS reaches end of life or is replaced, IT teams need to preserve all Xeams mailboxes before powering down the hardware. Univik Converter processes the copied Xeams archive into PST or EML so all historical email remains accessible after the NAS is gone.
Organisations moving from QNAP Xeams to Microsoft 365, Google Workspace or another cloud mail platform need their historical emails in PST or EML format for upload. Univik Converter produces import-ready output for all major cloud migration tools without any intermediate reformatting step.
Regulated industries must retain business email for three to seven years. Xeams already archives every inbound and outbound message, so converting that Good repository to PDF or EML creates a compliant, readable archive independent of the NAS. Each PDF email record includes all headers and metadata required for audit trail and legal disclosure purposes.
When employees leave, IT managers need to archive their Xeams mailbox before the account is removed. Univik Converter exports the departing employee's full mailbox including sent items, drafts and any custom folders to PST or EML for handover to their manager or storage in the compliance archive.
Organisations running Xeams use Univik Converter to validate repository backups by converting them and verifying email integrity. Converting to EML or PST and spot-checking emails confirms that the backup is readable and complete before a real disaster makes this question urgent.
Xeams Server Reference
What Xeams is, how it stores email and what the conversion process involves technically.
Xeams is a secure email server from Synametrics Technologies that runs on Windows, Linux, macOS and on QNAP NAS through Container Station. It provides SMTP, POP3 and IMAP services and can run as a full standalone server, as a spam firewall in front of Exchange or in hybrid mode. Many QNAP owners run Xeams as the mail server for their business.
Xeams stores every message as an individual RFC822 (MIME) file inside its email repositories. Since RFC822 is an open standard, the data can be read by any MIME-compatible tool once the folders are copied off the NAS. Xeams to PST conversion is the most common operation after a QNAP email export.

QNAP Xeams Version History
Xeams began as a Java spam-filtering server that sits in front of Exchange and other mail servers, then grew into a full email server with built-in SMTP, IMAP and POP3, end-to-end encryption, clustering and a web client. It runs on QNAP through Container Station, giving NAS owners a self-hosted mail server.
