The quality that makes OST one of the best choices over PST for MS Outlook is its seamless work experience. An OST file can work offline. If the server has any errors, you can still work on OST. Whatever changes made offline are saved to the Exchange Server as the connection is re-established. An OST file stores emails, notes, journals, events, address book, tasks, etc.
While working offline, OST doesn’t allow users to download emails, attachments, or send new messages but they can compose or read emails, schedule meetings, create appointments, delete or move emails, etc. An OST file is a cached copy of all data.
