iPhone not downloading pictures in emails
I have an iPhone 11 that is running iOS 16.5.1. Recently it has stopped downloading photos in emails - I just get a "winmail.dat" file. I have tried absolutely every fix I can find, but the problem persists. I have plenty of Cloud storage, I have reset network settings, I have turned iMessage off and then back on, everything. I have tried sending test photos to my own email (on my PC) to see if the photos will come through on emails I open with my iPhone, but they do not. I can access the "Sent" mail folder with my iPhone and the photo I sent is there, but it is not on the email in the Inbox.
I am at my wits' end. I need some help getting this resolved.
