If you’ve been using Microsoft Outlook to manage your emails and calendar, you might have come across OST (Offline Storage Table) files. These files allow you to work offline with your email data when connected to an Exchange server. However, when it comes to importing OST files into Outlook, many users are left wondering about the process and its limitations. This article will guide you through understanding OST files and how you can manage them effectively.

What is an OST File?

OST files are created by Microsoft Outlook when you configure your account to use Microsoft Exchange, Office 365, or Outlook.com. They allow you to work with your emails, calendars, and contacts even when you are not connected to the internet. Changes made while offline are synchronized with the server once you reconnect.

Can You Import OST Files Directly into Outlook?

The short answer is no. Microsoft Outlook does not support direct import of OST files. This limitation is mainly because OST files are tied to a specific user profile and Exchange server. However, there are ways to recover and use the data contained in an OST file.
