    Use the Windows search function to get there (see image)
  2. Click on “Mail (Microsoft Outlook)”
    This item is only visible if you choose the view with large or small icons at the top right, not the category view (see image).

    Choose a name for your profile and confirm. Click “Apply” to continue.

    That is not what you see? Then you have already created a profile and the configuration is slightly different, see below.
