Change it back so that email replies originate with the email address the email was received to.
I have two accounts that I use from my main hotmail account. Whenever I reply to emails received to my secondary account, I have to change the "From" email address back to my secondary email EVERY TIME, when it used to automatically use the address that the email was originally sent to. It's very annoying, and wastes a lot of my time, and is confusing for my clients when they are getting emails from my main personal account, instead of my work secondary account.
Same here. I quit using the Beta version because of this, but now there's no going back. Please fix this!
