Sometimes, you are surprised when functionality that should obviously have a configuration point does not. That is definitely the case when it comes to the default save path for Outlook attachments in Microsoft Outlook 2016

  • Create a String Value called “DefaultPath” and make the value be the folder location you want

Below is a screenshot of what your registry editor should look like after you’ve added the path:
