Can I switch back to a previous version of Yahoo! Mail?
Once you have upgraded to the new Yahoo! Mail, it is no longer possible to switch to an earlier version. We apologize for any inconvenience this may cause.
Older versions of Yahoo! Mail are being phased out over the next few weeks, so all users must upgrade.
We know it’s an adjustment to get started in a new interface, but we think it’s worth it: the new Yahoo! Mail is fast, easy to use, and available anywhere. To help you get started, see our overview of the new Yahoo! Mail.
