Yes, you can switch between the all-new Yahoo! Mail and Yahoo! Mail Classic. We understand that it's not easy to switch away from a format that you're comfortable with. So we made it easy to switch back whenever you want. You can switch to the new version and back to the old as often as you want. We hope you'll see how much the new Yahoo! Mail improves on the old version. But until you agree, here's how to switch back.
To switch to Yahoo! Mail Classic click the Options link in the upper right corner between Help and Mobile, then click the Switch to Yahoo! Mail Classic link.
To come back to the All New Yahoo! Mail, just click All-New Yahoo! Mail between Sign-Out and Help in the upper-left corner of your Yahoo! Mail page.
