eSoftTools Outlook PST Recovery Software of our client-architect conversations take place in MS Outlook, where I own a small construction business. One day, Outlook stopped running. One of my IT friends recommended the eSoftTools MS Outlook PST recovery software that recovers PST files to Outlook MBOX, EML, EMLX, MSG, HTML, Gmail, YahooMail, and Office 365. looked over the website and saw that if I wasn't pleased, the company gave a money-back guarantee. As a result, I gave it a shot and was pleasantly surprised. The app retrieved all of my data in minutes and exported PST to Office 365. I was overjoyed, even though my old ANSI files were also restored. Both computers should have this software installed.
