Windows 10: Email draft Disappeared While Typing

While I was in the process of typing on a very long email draft I looked up at the screen on my pc and everything was gone except the last 3 words I had just typed. I have been working on the email for 2 days. So I have had no problems going back to my draft and adding to it. I don't have a clue what happened or how to recover it. I hope someone can help!!!

:)

 

Why did my email draft disappear?

If I click on what looks like the Windows logo in the lower left corner of my screen and select "Mail", or if I click on the little envelope at the bottom of the screen, a blue rectangle comes up with a little envelope in the center. I get a list of emails.
I just happen to be using Yahoo. If I select an email I can reply to it, or, if it is a draft, I can add to it. In some cases, I am working on one of these emails for a long time, adding to it occasionally, when the computer freezes, or perhaps just the email
draft freezes. I can't type anything. Sometimes there is a rotating blue circle. The problem only clears up if I click on the little envelope. But then the blue rectangle comes up again, meaning I have to hope the draft is still there. Even if I recognize
the first few words in the list of emails on the left side, sometimes what is there disappears after I call up the draft to continue working on it, and when that happens, the familiar words disappear in the list. I don't understand what happened to my draft.

 

Why did the email draft disappear?

By clicking on a small envelope at the bottom of the screen or clicking on the button that looks like the Windows logo in the lower left corner of the screen and selecting mail, I get a blue rectangle with a little white envelope in the middle and eventually
a list of emails on the left (in this case Yahoo). If I select one of the emails it appears on the right side and I can reply to it. Sometimes I can't add to this email because it freezes. Sometimes this is accompanied by a rotating blue circle. Sometimes
I can't do anything until I click on the little envelope at the bottom of the screen again, and everything comes up again. There is usually a draft which I can select from the list on the left and continue working on. But on more than one occasion, that draft
has just disappeared. Even if the first few words of the draft appeared in the list on the left, they disappeared on the right and then in the list on the left. What happened?

 

WP10 is not saving body of draft emails

When typing an email and interrupted, then returning to that email in drafts, the To: address remains as well as the topic, but the body of the draft email does not appear.

Is there a save button that I've been missing? Or some steps I'm doing wrong?

What a pain!
