Don’t show the preview when clicking an image file set to signature
It is very disturbing that the preview shows up when a recipient clicks an email signature with an image if a sender already set an image on the signature in Outlook on the web.
Outlook client doesn’t act like this.
So, don’t show the preview of the image which is set in the signature as it is not attachments.
Previously, there was no such a behavior, so please reverse the functionality immediately. We prefer the behavior like Outlook does.
