Definitely YES! Anyone can move an OST file. In the following, we will show you how to complete the task:

Method 1. Use Symbolic Link

  • Select Microsoft Outlook and copy the OST file from the default location to the new location.
  • Next, open Command Prompt as administrator and execute the following command: mklink "C:\Users\user\AppData\Local\Microsoft\Outlook\[email protected]” “E:\MyOSTDataFile\[email protected]
  • That will create a symbolic link to move the OST file. And a shortcut is created at the default OST file location that redirects Outlook to the new location.
  • To change the symlink, delete the shortcut.

Method 2. Use ForceOSTPath Registry Key

  • First, back up your OST file, remove your Outlook profile, and close Microsoft Outlook.
  • Hit Windows + R, and enter regedit to open the Registry Editor window. Then choose the right path based on the Outlook version installed on your system.
  • Next, right-click on Outlook, choose the New option, and then select Expandable String Value.
  • Right-click on NEW Value#1 and choose the rename option. Once done, open File Explorer and move to your desired location. Just copy the path and paste it into the Value date field of ForceOSTPath.
  • Finally, exit the Registry Editor and restart your system. That's all.
