You can use MKLINK command (Symbolic Links) to repoint the OST file. Outlook will be still pointing to original location, but during access, it will be redirected. On the original path will be created only one shortcut.
To create symbolic link:
- Move the OST file from the default original location to a new location
- Open the elevated Command Prompt
- Execute the mklink command: mklink “old_path” “New_path”
