OST file is the Offline Storage File of Microsoft Outlook, which is automatically created when we configure an account at the client end, connected to Exchange Server. The OST files are same as PST files (Personal Storage Table). OST and PST files, both, are created at same location. PST file is directly synchronized with the network instead of Microsoft Exchange Server and user can read the archived data.
So if we want to migrate OST file out of Exchange Server environment, we need to convert OST file to PST, so that, we can access the mails and documents without connecting to Exchange Server. Extract OST to PST process can be carried out in local system without using any third-party tool.
The above method is based on Microsoft Office 2003 Professional Edition. Options may vary in Microsoft Office other versions.
You can convert OST file to PST till the time you are connected to Exchange Server. If you are disconnected from Exchange Server or your Exchange Server is damaged, then you need a third-party OST to PST conversion tool.
