I was searching for software that can repair my multiple PST files altogether. I am having 10+ PST files which are large enough. And I wanted to repair corrupted PST files without installing MS Outlook in my system. The SysTools Outlook Recovery software worked perfectly fine. And one of my PST files was having encrypted email messages in it. The tool functioned amazingly and helped me to decrypt all the email messages without any loss. It is a highly efficient and simple tool. It has a simple user interface and the working process in clear and simple. It has many more advanced features if you want to know more about it. Like, recover permanently deleted Outlook data items easily, the Selective Export option and multiple export file options and many more.
