Many users prefer saving their data like emails, contacts and calendars on MS Outlook Server. All these data are stored in OST and PST formats on the Outlook Server. But the OST file can’t be viewed unless and until it is converted into PST format.
Sometimes the users go through such problem and they don’t know how to tackle it. Some of them try to convert OST format files to PST by using manual techniques and lose some data in doing that. So I would recommend that never try to convert Outlook OST to PST manually because that can cause huge data loss from the file.
So the other alternative to that is to change OST to PST by using a third party software. The reason for using that is the software converts the file without causing any kind of data alteration. You can easily convert the file by yourself.
There are many other uses of the tool. It is compatible with all the versions of Outlook and Windows. It deeply scans the file before converting it to PST format. Once the scanning process is done then the file gets converted and you can save it in PST format.
