Outlook data files categorized as OST and PST are undoubtedly the fundamentals of MS Outlook. PST files come into use when you work with Outlook and having POP3 or IMAP access of a mail account. PST files reside on the local machine of the user and store all the Outlook data present in the user’s mailbox.
OST file on the opposite fence comes into existence when the user uses Outlook with Exchange Server. It is the replica of the user’s mailbox data saved on server. Similar to a PST file, all the items like mails, attachments, calendars, contacts, etc are stored in the OST file.
What does OST files do?

You can configure Outlook to store the local copy of the data in a file termed as Offline Storage Table or OST file. The OST file provides user the facility to work with Outlook in offline mode as well as when there is no internet connection or the user tends to be offline. These OST files then get synchronized with the Exchange server once the internet connection is available. As already mentioned these OST files are the replica of the Exchange server mailbox. These OST files prove to be beneficial in cases of:

- Synchronization issues with Exchange server
- In case of Exchange mailbox deletion
