Vanished email text

In Windows 10, it sometimes happens that a text typed in an email suddenly vanished as soon as I type the last word in the text. Why?

Have tried Ctrl + Z, but nothing happened.

I also tried the Re-cycle bin and Drafts, but again no luck.

Can you please help?

My thanks in advance.

I vaguely recall occasional problems with writing emails a couple years ago but the problem seemed to vanish. Perhaps in settings be sure you save email to a Draft copy every minute or so. This might help prevent the problem in its entirety.
Another alternative is to write into a text document first and then copy-paste into the email. Perhaps NotePad or Word.

Many thanks again for your prompt reply, and do, please, pardon me for replying rather
late. At age 79, I have become a slowcoach, and forgetful, too...perhaps the price one has to pay for living longer?!...

Your method worked very well indeed. I can now save the text to DRAFTS, and then send it off quite easily.

Kind regards.

Joe
