Convert OST to PST

Summary: This blog provides an overview of all the viable ways for converting OST to PST. All of the methods described are easy to use and are the most expedient ways to convert OST to PST.

All mailbox items are saved in Microsoft Outlook’s data files (OST and PST). Offline Storage Table files, or OST, are files that keep a duplicate of a user’s Exchange mailbox on a local workstation and allow users to work offline. All modifications are merged with the server whenever the connection to the server is reestablished. When a new Outlook profile is formed, PST files are created automatically, and they act as the repository for all local mailbox contents.

Why is it necessary to convert an OST file to a PST file?

  • Data Transfer
  • Exchange Server crashes or fails unexpectedly.
  • Exchange Server Maintenance
  • Recovering data
  • Corrupted mailbox
