Outlook Web Client Html Email Images And ImageProxy.mvc

I'm having a problem with images in html emails in Outlook web client. When a you put a image like this:

Solution 1:

Accidentally we discovered that proxifying on Microsoft's mail services applies only for HTTP images, not for HTTPS ones. So if you have HTTPS endpoint just use it prior HTTP one for images.

Solution 2:

Solution 3:

I faced the same problem. Changing http in https made the image appear correctly.
