Upgrade Yahoo Messenger
Yahoo Messenger 11.5 and prior versions are no longer supported. Please upgrade to the new Yahoo Messenger, which offers a faster and more reliable platform for group conversations. The update is available for iOS and Android. You can also use Yahoo Messenger through your browser. Right now, the new Yahoo Messenger isn't available for Mac or Windows.
After you upgrade, you'll still be able to chat with all your friends. However, you won't be able to send or receive photos, or "like" or unsend messages, with friends who haven't upgraded.
