Outlook OST to PST conversion helps users recover mailbox information saved in an OST file when the original Outlook profile or Exchange connection is inaccessible. OST files are associated with particular mail accounts and are not independent. Using Outlook OST to PST, individuals can import information into any Outlook profile and access emails, contacts, calendar, tasks, and attachments without relying on the server. This is particularly helpful when corruption of profiles or when a server is in fail mode or when migrating to another account.
