The SYSessential OST to PST conversion tool makes the task of moving large volumes of information easy and efficient while dealing with email migrations. The utility helps you convert your offline OST files to PST format and other common formats. By doing this, you save yourself lots of storage space and your time. The software allows you to choose the specific folders that should be converted, and you can see the items in the selected folders on the screen before you begin converting them. Your folders will retain their hierarchy, and the original contact lists will be maintained during the entire conversion process. Moreover, the utility works entirely by itself and does not require any assistance from Outlook or any server. Independently works on all Windows versions (7, 8, 10, 11)
