You can use this method to move the Outlook OST-file to the new location.

In this case, a symbolic link is created for OST-file in its original location on the system drive(c:\drive) which points to the file present on the data drive.

Steps to create symbolic link are listed below assuming an example with the OST-file name as datafile.ost, and the location to where OST-file is shifted as D:\Documents\Outlook Files.

mklink “C:\Users\%username%\AppData\Local\Microsoft\Outlook\ datafile.ost ” “D:\Documents\Outlook Files\ datafile.ost “
