Can the Barracuda Message Archiver import historical emails?
Yes. The Barracuda Message Archiver can archive emails from PST files, as well as active emails currently on an email server. To ease the archiving process for Microsoft Exchange servers, an email administrator can use Exchange Import from the Barracuda Message Archiver. For other standards-based email servers, the Barracuda Message Archiver supports the import of emails currently on the email server through both POP3 and IMAP.
