It is easy to access Outlook mail objects, such as e-mails, tasks, journals, attachments, appointments, and messages without Internet connection. The overall credit goes to the OST files. These files allow you to use mail objects without Internet connection. Using the OST file is the same as using MS-Office file. Whenever you connect with the Exchange server, all the data of the OST file gets automatically converted to PST. But sometimes, it happens you are unable to use mail objects because you fail to synchronize OST files with exchange server. So, there is a need to convert OST to PST file. For conversion, use a third party OST to PST converter tool.
