People had been facing problems opening outlook pst files without Outlook until a few days ago, but it had some issues, so I switched email clients. Following that, a friend advised me to try Office 365. Then I attempted to switch Outlook to Office 365, but I had a PST file and needed to change the file extension, so I downloaded eSoftTools Software to convert the PST file to Office 365, which worked flawlessly. Users will find its automated tool easy to use and understand, thanks to a simple recovery process that requires no technical knowledge. It's dependable and quick, and it can save data in the original or customized format.
