OST files are the offline storage files created by Microsoft Outlook to store a copy of your mailbox data, including emails, contacts, and calendar items, on your local computer. Over time, these files can grow large in size and take up a considerable amount of space on your computer’s hard drive. If you are running out of disk space on your current drive and want to move your OST file to another location, this blog will guide you through the process.

So, let’s get started without further delay!


An OST file is a copy of your Exchange mailbox that is stored on your hard drive. This copy can be accessed when you are working offline or have a slow connection. Once you are back online, any changes made to the OST file are synchronized with the Exchange server.

Why should you move the OST file to another location

The OST file contains a lot of important data, such as emails, contacts, tasks, etc., for a user. It is created when an IMAP or POP account is configured in Outlook. Users can work offline, and all their changes will be saved in the OST file. This is very useful when there is no internet connection available.

However, some situations exist when users want to transfer their OST file to another location. A common reason for this is that the OST file becomes corrupted, and Outlook cannot open it. Users can create a new OST file and set up their account once more if this occurs. All their data will be downloaded into the new OST file.

Some other reasons why users might want to migrate their OST file is if they are changing to a new computer or upgrading to a newer version of Outlook. If that’s the case, they can transfer the OST file to the new location and reconfigure their account. By doing so, all their data will be downloaded into the new OST file.

Advantages of moving OST file to another location

There are several reasons why you might want to move your OST file to another location:

  • The OST file may become corrupt if you are using an older version of Microsoft Outlook. You will need to move it to another location to continue using Outlook.
  • For it to work with the new Outlook version, you may need to move the OST file when upgrading to a newer version of Outlook.
  • Suppose you are moving an OST file from one computer to another location or copying OST file data into a new system for hardware recovery or any other reasons. In that case, you will need a converter to convert OST file format.

Loopholes of the Manual method

Can I use the automated tool to move an OST file to a different hard drive?

Yes, you can move an OST file to a different hard drive. However, we recommend backing up the OST file before doing so. That way, if anything goes wrong during the transfer process, you’ll have a copy of the original file that you can fall back on.

What happens if I try to open an OST file after moving it manually?

An error message that the file is “in use by another program” may pop up if you attempt to open an OST file after moving it. Outlook has a lock on the OST file while it’s open, which causes this problem. To prevent this error, close Outlook before relocating the OST file.
