Log in to the Barracuda Message Archiver
Access the web interface with administrator or auditor credentials
Open your browser and navigate to your Barracuda Message Archiver web interface URL. This is typically the appliance IP address or hostname, for example https://barracuda.company.com. Log in with your Administrator or Auditor account credentials.
Navigate to BASIC → Search
The Search page is the central hub for both searching and exporting
Click BASIC in the top navigation bar, then click Search in the sub-navigation. This opens the message search interface where you can search the archive and initiate exports. The Tasks and PSTs & Tags tabs on this page are also where you monitor exports and manage tags.
Search for Messages to Export
Use the search form to narrow down the messages you need
Enter your search criteria in the search form. You can filter by sender (From), recipient (To), subject keywords, date range and other fields. Leave fields blank to match all values. Click Search to run the query.
Select Messages and Click Export
Choose all or specific messages from the search results
After the search runs, use the checkbox in the header row to select all messages, or check individual rows. Once messages are selected, the action toolbar appears with the Export option. You can also choose Current Search Results to export everything matching your search without selecting individually.

Configure Export Settings
Choose format, chunk size, EML naming and journal wrapper options
Clicking Export opens the export configuration dialog. This is where Barracuda's unique options become important. Set the format, chunk size and EML naming convention, then decide whether to enable journal wrapper preservation for Exchange-journaled messages.

Monitor and Download from the Tasks Tab
Track export progress and download each chunk as it completes
After clicking Export, the job runs as a background task. Click the Tasks tab on the Search page (or navigate to BASIC → Search → Tasks) to see all running and completed export tasks. Large exports split into multiple chunks — each chunk appears as a separate download row on the Tasks tab.
Scheduled Exports
For ongoing compliance workflows, Barracuda supports Scheduled Exports that run automatically on a recurring basis. Instead of manually running a search and exporting, you define a Saved Search and set it to export all new data that has been archived since the previous run.
Scheduled Exports are configured under POLICY → Scheduled Exports. Both Administrators and Auditors can set them up. Each Scheduled Export is based on a Saved Search from the BASIC → Search page, and each run produces a PST file available for download from the Scheduled Exports page.
What is in a Barracuda Export?
Barracuda delivers exports either as a PST file or a ZIP file containing individual EML files. Large exports are split into multiple chunks of the size you selected. Each chunk is a separate downloadable file.
| Property | PST Export | ZIP/EML Export |
|---|---|---|
| File format | PST (Microsoft Outlook) | ZIP containing EML files |
| Opens in Outlook? | Yes — import directly | No — needs conversion |
| Chunk size options | 800MB, 4.7GB, Custom | 800MB, 4.7GB, Custom |
| EML naming | N/A | Numerical, Date, or Date/From/To |
| Journal wrapper | Included if enabled | Included if enabled |
| BCC recipients | Visible in journal envelope | Visible in journal envelope |
| Folder data | Included for LDAP users | Included for LDAP users |
Convert Barracuda Exports to PST, MBOX or PDF
Barracuda ZIP/EML exports cannot be opened in Outlook. Even PST exports may need normalisation before clean import. Univik Barracuda Archive Converter handles all chunk sizes, naming conventions and journal wrappers:
- Outlook / Office 365 — Convert ZIP/EML chunks to PST with journal wrapper data intact
- Thunderbird / Gmail — Convert to MBOX format
- Legal / Compliance — Convert to PDF with BCC and journal envelope preserved
- Per-user output — Separate PST or MBOX file per user for Office 365 import
Load all Barracuda PST or ZIP/EML chunks at once. Handles all chunk sizes (800MB, 4.7GB, custom). Detects journal wrappers. Flags stubbed attachments. Per-user output. 100% offline.
Frequently Asked Questions
0001.eml, 0002.eml), Date (timestamp string: 20260322093014.eml), and Date/From/To (full string containing date, time, sender and recipient: 20260322_john_client.eml). All three are automatically detected and handled by Univik Barracuda Archive Converter.
Troubleshooting Common Issues
The Export button is not shown by default for all users. An administrator must enable it under BASIC → Administration → Search Page Settings. If you are an administrator and still cannot see it, ensure the setting is enabled for your own admin role. Also make sure you have messages selected before looking for the action bar — it only appears after selection.
Exports run as background tasks and may take several minutes to appear. Refresh the Tasks tab. Large exports of tens of thousands of messages can take hours to process. If a task does not appear after 10 minutes, try submitting the export again. If the Barracuda appliance is under heavy load from other tasks, queued exports will start once resources are available.
Set a smaller chunk size (800MB instead of 4.7GB) so each download takes less time. Alternatively, enable SMB share access from the Advanced settings to copy files directly over the network without browser download limits. For PST files larger than 250MB, Barracuda recommends using the Queued Import method or SMB share rather than the web interface download.
EML files are plain-text RFC 5322 format. Windows may not know which application to open them with. Right-click any EML file, choose "Open with" and select an email client such as Windows Mail, Outlook Express or Thunderbird. Alternatively, use Univik Barracuda Archive Converter to batch-convert the entire ZIP to PST or MBOX instead of opening individual EML files.
BCC recipient data is stored in the Exchange journal wrapper, not in the standard email headers. When re-exporting, make sure the Preserve Journal Wrappers toggle is enabled in the export configuration dialog. If you have already exported without this option, you will need to re-export with it enabled to include BCC data. Also confirm that your Barracuda is configured to archive via Exchange journaling — if it archives via SMTP relay instead, journal wrappers may not be present.
Load all Barracuda chunks at once. Handles 800MB and 4.7GB sizes, all EML naming conventions, journal wrappers and stubbed attachments. Per-user PST output. 100% offline.
