Why aren't pictures displayed in my Win10 Outlook App?

[Windows Central Question]

Pictures not displayed in Win10 Outlook App

For some reason no images are displayed in the Win10 Outlook app. If I view the same emails in the Outlook web app the images are displayed. In the Win10 app this message is displayed instead of the images: "The linked image cannot be displayed. The file may be removed, renamed or deleted..." etc.

Grateful for any insight.
