eSoftTools Outlook Recovery Software can import Outlook PST files and many more file formats into Zimbra Desktop. This utility allows users to effortlessly import Outlook PST files into Zimbra Desktop. This tool can also import PST files directly into Gmail, Yahoo Mail, Office 365, and other IMAP-based email accounts. You will be able to see a live preview of the contents of the PST file inner folder, including emails, contacts, calendars, appointments, and so on if you start the conversion process before that time. It can also get back emails, contacts, calendars, and attachments from damaged or password-protected Outlook PST files.
