Convert OST to PST

The Outlook program uses two types of file formats: OST and PST. The PST file includes all of Outlook's mail flow data and is kept on the device's hard drive, but the OST file is an identical copy of Exchange Server data and is stored as a local copy on the user's device. It is kept in order to store Exchange data for offline use.

Although an OST file enables users to view Exchange Server mailbox items in Outlook when offline, some circumstances necessitate the conversion of OST to PST file. In this article, we will talk about such reasons and free manual solutions to convert OST files.

Why do users need to convert OST files to PST?

There could be several reasons to convert an Exchange OST to PST file. A few of these factors are addressed as follows:

  • Many times, Outlook users suffer from various errors, like email sending and receiving errors, or others. In these situations, users convert their OST files' mailbox data to PST files to prevent any kind of data loss.
  • Because of integrity problems, a large OST file is vulnerable to corruption. Therefore, users can convert some of the OST mailbox data to PST to avoid the corruption.
  • When the Exchange Server fails due to corruption or other factors, it becomes very helpful to you to convert your OST data to PST for backup purposes or other reasons.
  • If MS Exchange data is accidentally deleted or lost, you can perform a conversion or repair OST files.
  • Changing from one system or operating system environment to another, taking a backup of your OST data to PST is more helpful.
