It looks like the SERP doesn't like one particular email we received from our client. Other emails opens up as usual.
In the MS outlook the same email doesn't look unusual. It has 2 attachments, one html, another one - PDF. The email was sent from Mac.
html attachment has some strange reference to the image:
