Providing Two Free Ways to Export OST File

Microsoft Outlook is one of the most advanced email clients supporting multiple features. MS Outlook saves its data in OST and PST file formats. An OST file or Offline Storage Table allows users to work offline. In other words, Microsoft Outlook, in the offline (Cached Exchange) mode, stores the Exchange mailbox data in a local file called OST. As the Exchange connection is reestablished, all the changes in the OST file are saved to the server mailbox. Since OST files are saved locally, they are unaffected by Exchange Server crashes and disasters.

Here are some scenarios when exporting an OST file to PST becomes very helpful:

  • A few Exchange mailboxes get deleted from the server
  • Looking to create a backup of Exchange mailboxes
  • When the Exchange user are looking for rebuilding his OST file, but the user has some unsaved data in the OST file
  • When OST files become oversized, conversion from OST file to PST can save the data from corruption
  • Users have several options to convert OST data to PST. They can log in to Outlook with the same Exchange profile. Some native methods are helpful to export from one file format to the other.
    • Export mailbox data to PST
    • Archive OST emails
    • Convert OST mailbox to PST Using a Third-Party Tool
