MS Outlook, one of the most widely deployed desktop email client, which deploys two data files for storing its entire data i.e PST or OST files. PST files are used for data storage when Outlook is configured with IMAP or POP3 protocol and OST file comes into use when Outlook is configured with Exchange Server.
This blog illustrates the method by which user can extract emails from OST files to PST manually as well as we suggest you some commercial utilities.
Even though, both OST and PST files are associated with the same email client, they differ in their structure and functioning. Due to this very reason, the OST file data cannot be accessed in IMAP/POP3 account. Moreover, OST file data cannot be retrieved to PST format and vice versa. Therefore, the users need to opt for other solutions when it comes to extract OST file to PST.
OST or Offline Storage Table is associated with Outlook when it is used in synchronization with Exchange Server. It stores a replica of the entire data stored in Exchange serve mailbox with which it is associated.
For every mailbox that resides on Exchange Server, a separate OST file is created for each mailbox, when Outlook is configured with Exchange. An OST file cannot be opened, exported or accessed in any other Outlook profile or machine except the profile or machine in which it was created.
