How to Import OST File to Microsoft Outlook

The article intends to explain how an .ost file can be imported to Microsoft Outlook. The method described here is simple and reliable. It is, however, advised that users follow and implement the instructions accurately to avoid running into problems. This will also save them time that would otherwise be spent looking for Microsoft Outlook support.

An .ost file (offline storage table) is an offline folder that stores the entire Outlook data on Microsoft Exchange Server (MES). It allows users to work in offline mode when MES is not connected or available. The changes are later on synchronized when user connects to the MES. If you are searching for help on importing .ost file(s), chances are that you are planning to reformat your computer. The below mentioned guide will help you do so in the easiest manner and without the help of Microsoft technical support.


Since .ost file is just a mirror image of the user’s email account on MES and not a backup, it cannot be restored. It can rather be converted to a.pst (personal folder) file that can be imported to Microsoft Outlook for further use.

Download and install a free or paid tool that converts an .ost file to a.pst file from a trusted website. There are a number of tools available on the internet including SysTools OST Recovery, OST2PST, Kernel OST to PST Converter, and Recovery Toolbox for Outlook among others.

You can also check Google for more search results on OST to PST file converting tools. Once you have concluded on any tool, download it from its official or any trusted website. When prompted save the downloaded file to a convenient location like desktop in the computer. Double click on the downloaded file’s icon and follow the wizard’s instructions to install it and initialize the conversion process. Wait until the process finishes. When the file is converted to a.pst file (you will see an icon on the desktop or other chosen location), import or copy it to Outlook. Now you can use your valuable data as desired in Outlook.

Now take a backup of your entire Outlook data or other important data to an external flash drive or CD etc. and reformat your computer (if you wanted to do so). Once you are done reformatting, reinstall Outlook along with other applications. Setup and configure your email account and copy or import all your Outlook data.

Additional Tips:

It is recommended to download such software only from trusted websites so as to avoid carrying along infections to your computer. A majority of tools come embedded with spyware or viruses etc. that can cause harm to your computer.
