PST Import and Configuration

A PST file is an MS Personal Storage Table, and contains email messages exported from Microsoft Outlook. Some PST files also contain additional Microsoft Outlook items such as Appointments and Contacts.

You can import the contents of any PST file from Microsoft Outlook 2000 (and later) into the Barracuda Cloud Archiving Service from the Mail Sources > PST Import page. Password-protected PST files are accepted as well as non-password-protected files. To allow users to import their own PST files directly from the Mail Sources > PST Import page, set Allow PST File Uploads to Yes.

Before importing PST files, ensure that LDAP services for your Active Directory (AD) server are configured. This ensures that SMTP aliases associated with the message sender and recipients are resolvable.

Barracuda Networks highly recommends running your PST files through scanpst.exe prior to uploading the files to the Barracuda Cloud Archiving Service to ensure there is no data corruption. For more information, refer to the Microsoft Support article https://learn.microsoft.com/en-US/outlook/troubleshoot/data-files/how-to-repair-personal-folder-file.

The Barracuda Cloud Archiving Service can accept one PST file at a time for immediate import from the web interface. Files that are imported directly in this manner are processed immediately and their contents is added. Because processing files for import can be resource-intensive, Immediate Import supports files of less than 250 MB in size.

To upload PST files larger than 250MB, upload multiple PST files, or large ZIP files, administrators can enable SFTP transfer from the Advanced > SFTP transfer page. For more information, see How to Import PST and ZIP Files.
