Why suddenly is my email letter attached to a letter I'm answering?

I used to be able to choose whether my original letter would be attached or not. I chose not to have it attached. Now when I answer someone's email mine or their original letter is on the reply letter. I can't find the option to change this back to the way I had it.

That's pretty standard all across the Internet.





A couple of mail services did allow you to choose ---"don't include original message". Yahoo WAS one them, but I understand they are in the process of removing that option.


All accounts haven't been changed ---yet--so maybe you still have it. (as described in Tom's answer above)
Reply:Open your Yahoo! Mail account, Click on Options near the upper righthand corner, then click on General Preferences in the middle column. Scroll down to Message Actions and click on the circle by Replying labeled Don't include original message when replying.





Then comes the important part: Click on Save at the bottom of the page. If you make changes and do not click on save, the changes will NOT take effect.
