How to Convert OST to PST without Outlook?


Converting OST (Offline Storage Table) files to PST (Personal Storage Table) without using Outlook can be a challenging task. OST files are used by Microsoft Outlook to allow users to work offline and synchronize changes when they reconnect to the server. However, there are instances when you may need to convert OST to PST without having access to Outlook, such as when you want to migrate to a different email client or recover data from a corrupt OST file. In such cases, a reliable third-party OST to PST converter tool like Xtraxtor OST to PST Converter can come to the rescue.

Reasons to Export OST to PST without Outlook

There are several reasons why you might need to convert OST to PST without using Outlook:

  1. Migrating to a Different Email Client: If you are switching from Outlook to a different email client that doesn’t support OST files, you’ll need to convert OST to a more universally supported format like PST.
