Whenever an OST file is created in Outlook, it contains an encrypted token, that is associated with the configured account which is used to create that particular OST file. Next time, when the account changed with a different email service like gmail, yahoo etc, then the token associated with OST file becomes no longer with old account and the Outlook will not able to recognize that OST file. In such situation, the OST file becomes orphan and there would be no workaround exists.
How to Repair Damaged OST file and Access Its Data?
After MS Outlook 2010 and later releases, you can repair a corrupted OST file by deleting and re-downloading the OST file from Exchange Server. Similarly, the damaged OST file of previous versions of MS Outlook 2010 can be fixed by Outlook OST integrity checker (scanost.exe). But, there is no recovery guarantee of highly corrupted OST files, as it fixes minimum corruption issues. Also, it will not be useful for fixing orphaned OST file issues. Hence, there is no workaround to convert orphaned OST file to PST file using scanost.exe.

Moreover, MS Outlook data items that are stored on the system are named as Outlook Data File with both .pst and .ost file format. Now, why there are two file formats to save data? What exactly the difference between PST and OST files used in Outlook? To resolve all such queries, a deep comparison of OST vs PST is done here.
In MS Office Suite, Microsoft Outlook is the widely used application among the business users. It is an email client that allows users to exchange information in an organization using its mailing service.

PST file format is created for each user account configured in Outlook to maintain copies of emails, contacts, calendars, tasks, notes etc. If Outlook is connected with Exchange Server, then all items are delivered to and saved on the server. However, if a user wants to have access to data when not connected server, then OST file or Offline Storage Table is stored on the system.
Both OST and PST files are data files of Outlook but they are completely different from each other in many ways. Thus, to understand both in a better way, the difference between OST and PST is done in the following section of the blog.

The main purpose of OST file is to allow users to work in an offline mode. It is mainly used by the users who want to keep their data safe and secure. If one is not connected with the Exchange Server, then also with the help of OST file one can work offline and work gets synchronized automatically when the connection is reestablished. Moreover, in the case of corruption in Exchange Database, a user can recover data from OST file saved on the drive. On the other hand, Personal Storage Table and PST file allow users in increasing the storage. It is the file that can easily be backed and can be accessed on any other computer also. In the case of large size PST file, one can easily split the PST file by date, year, size and much more. It helps users in managing their Outlook mailbox in the more synchronized way and prevent corruption.
