What is the reason why one should convert .ost to .pst in Outlook?

When the account is deleted and/or the Exchange server malfunctions or the profile is corrupted so that the data cannot be accessed in the outlook, the users have to convert .ost to .pst. OST files are not reusable and are offline caching files. In the same way, when you convert .ost to .pst, the information is made portable: it can be imported into Outlook every time. This conversion will maintain the mailbox, emails, attachments, and folders, and will allow further access to the valuable communication and business data without access to the initial email server.
