First of all thank you for the reply. Now for an update. I got the mail to open by highlighting it and clicking the relevant icon. I don't know why it did not occur to me to try that before posting except that I prefer to open emails with a double click and for whatever reason that was not working. I don't know what a raw view is or how one would see it and I would be interested in learning. As for a message not opening I would think that a minimally competent program would display a verbal message telling in detail why a message will not open and what if anything I can do about it. I have very little patience with a computer or a program that does not explain itself in detail when it does not do what I want. I really do try to be patient with computers because I do not understand them except at the level of an operator of software so I very much admire the people who can design and make hardware and software. But my first computer as far as I remember never balked on me without giving me an unmistakable indication of what was wrong and what I could do about it. The fact that I had to restart it at least every hour and a half did not keep it from being in my memory much better than any I have had since.

An email won't open. It's political and bulk but it did not go to spam even though ATT thinks it is spam. Anyway I want every email to open when I click it and I don't care if said email is spam or even contains malware. I would rather have disaster happen than be prevented by code on a computer leading it to not follow my instructions. Anyone got any quick thoughts on how to get this email to open and or how to prevent this problem in the future?

Can you see the raw view?  Sometimes mail is created with bad headers and PM can't display it properly.  If a previous server has removed a part that it thinks it malware, then it may end up as an empty message - I see a few of those.
