Converting an OST file to PST can definitely be useful when the original Exchange account is no longer available or when mailbox data needs to be accessed independently of the server.

One thing users should keep in mind is to verify that all mailbox items, including emails, contacts, calendars, and attachments, are preserved during the conversion process. It's also a good practice to create a backup of the original OST file before attempting any recovery or migration operation.

Has anyone compared the results of different conversion methods and noticed differences in folder structure or data preservation?
