If you're having trouble with Yahoo Mail not working on your Mac or PC and think something's wrong, follow our brief troubleshooting guide here to fix the problem.

How to Fix Yahoo Mail When It's Not Working

Before doing anything else, if you have an ad blocker installed, try disabling it and refreshing the page. Ad blocking software can sometimes prevent websites from loading properly.

If the problem persists, find your problem in the guide below and try the corresponding troubleshooting method.

If the Yahoo Mail website is very slow or the buttons and menus don't work

It is possible that the problem is related to your Internet browser. If you're using a desktop or laptop computer, make sure you're using a Yahoo-compatible browser (Firefox, Chrome, Safari, or Edge) and have the latest browser update installed.

There may also be a problem with your internet connection. Try running a speed test and check if other websites are equally slow. If so, move closer to your router or try resetting it.

Clearing your internet browser's cache can also help. If you're using a mobile device, make sure you're using the Yahoo Mail app and have the latest update installed.

If you're having trouble logging in

Have you ever signed in to Yahoo Mail on this device before? If not, there may be a problem.

If this is a new computer or mobile device and this is your first time using Yahoo Mail, you'll be prompted to verify your information. If you've made too many failed login attempts, your account may lock out for 12 hours before you're allowed to log in again.

If you are concerned that your account has been hacked, select the "Forgot password" option and change your password immediately.

If you can't send emails

You may just be making a few small mistakes. Emails that have been successfully sent will appear in your "Sent" folder, so check that first. If it's there, it's been sent. If the email is not there, check your "Drafts" folder - you may not have sent the email as expected. Check the spelling of the recipient's email address to make sure you sent it to the right person. Also, make sure you haven't blocked their address. Finally, ask the recipient to check their own Spam folder, filters, and blocked addresses list to make sure your email didn't hit any walls on its way to them.
