When an Exchange or IMAP email account is deleted, Outlook can no longer perform synchronization and the OST won’t be updated. You can’t access such OST files in another account as OST files are linked to the email account in which they’re created. Likewise, your old OST files can’t be accessed or imported into Outlook. This necessitates the users to convert OST into PST when they need to recover their Outlook mailbox data.

Microsoft Outlook gives options to export OST mailbox data to PST files. However, you can only export data from your active mailboxes. You can’t convert inaccessible or orphaned OST files. Also, manual OST to PST conversion is a time-consuming process and doesn’t always go as per the plan.
