Images are not displayed in incoming emails

Hello,

Since 10 days or so, Outlook 365 on my Win11 laptop does not display images anymore. See below placeholders having a red cross.

Note images from the same email are displayed alright in the New Outlook, in https://outlook.live.com/ and in Mail under iOS.

Of course I have already unchecked both options in File/Options/Trust Center/Automatic Download. See below.

What else should I do to get those images painted? Can anyone help?

Thank you!

Stefano
