1. Why Email App Isn't Working Mac Pro

Check the camera indicator light

1. Not receiving email. Once in a while, your Mail.app (sometimes referred to as 'Apple Mail' or 'Mac Mail'), stops receiving new mail. You may be able to verify that you are getting new mail via webmail, another email client or computer, or even via a mobile phone. When this happens, the fix is extraordinarily easy!
2. The team is working on a solution in a future update. If you’re able to upgrade your browser, the problem should be resolved. Or, if you’re not able to upgrade, Hotmail recommends using a different browser for Mac, such as Firefox or Chrome.

If the camera indicator light next to the camera flashes green on your Mac notebook, contact Apple.

Before you begin

There are a few things to keep in mind and check:

• When you make an iOS or iPadOS backup in iCloud or iTunes, it backs up your mail settings, but not your email. If you delete or change your email account settings, previously downloaded email might be removed from your device.
• Make sure that your device is connected to the Internet.
• Check with your email service provider to find out if there's a service outage.
• If you can't access your email, or you can't send and receive messages with your @icloud.com email address, learn what to do.

Check your email address and password

If Mail asks you to enter a password for your email account, make sure that your password is correct. To check your email address and password, sign in to your email provider's website.

If you still get a user name or password error, contact your email provider or system administrator.

Contact your email provider or system administrator

1. Contact your email provider or check their status webpage to see if there's a service outage.
2. Ask your email provider or system administrator if you turned on any security features or restrictions, like two-step verification, for your email account. You might need a special password or may need to request authorization from your email provider to send and receive email on your device.
3. Check your email account settings with your email provider or system administrator to make sure that they're correct.

Remove your email account and set it up again
