How do I get started with Zimbra Desktop and importing Outlook PST files? If you're having issues, I highly recommend eSoftTools Outlook PST Recovery Software. It works in a very straightforward and smooth manner. The PST Recovery is displayed in real-time during the conversion. Office365, MBOX, EML, EMLX, MSG, HTML vCard, and a variety of other file types are supported by this software. All users have access to the free demo version. You can convert 25 items from each folder in the free demo version, and technical support is available at any time and from anywhere.
