MS Outlook is an email client, widely used by business organizations, and offices for their communication purpose. Most users configure their account with MS-Exchange Server which works in synchronization and saves data in Offline Storage Table (.ost) file format. OST file contains data in offline mode on a hard drive.
When a user logs in with the IMAP account, every time data is synchronized and downloaded to the system in the OST file format. It helps to keep data up-to-date in the mailbox with new emails, reports, meeting requests, etc.
Sometimes when the User creates an account with IMAP configuration, then it also works as a web server-based application and stores synchronizing data in (.ost) format.
However, there are various situations when these files become inaccessible. To manage the situation, the user needs to change the OST file into another file format i.e. PST. So that data can easily be accessed in offline mode. In the below section, I am explaining 2 methods to convert OST to PST format.

There may be different situations when the user needs to convert an Exchange IMAP OST to PST format, Some reasons are discussed below:

2. Exchange Server Unavailable: Accessing mailbox data can be difficult due to Exchange Server maintenance and downtime. When data in the mailbox is saved with the .ost extension and synchronized with the server, it becomes inaccessible. To gain access to the data, the user must export their emails from OST to PST format.
3. When users export mailboxes from OST to PST, corrupted or accidentally deleted data can also be recovered.
4. Conversion of OST to PST is also helpful in data migration. In situations when the user wants to shift from one place to another place, it is easy to migrate PST data from one place to another place.
