Kindle Fire Email error: Unable to connect to server."

Hi,

I understand that you are unable to access e-mails through Kindle Fire. I will be happy to help you.

I suggest you to set up your account to your mobile device using ActiveSync. Please refer to the article below to know more about this.

You may refer to the POP3 or SMTP server and port settingsfound in the article below to address your concern.

Along with these, I suggest you to enable the two-step verification.

App passwords and two-step verification.
If you need an app password and already know how to use one, visit your security info page online to get an app password. To learn more about app passwords and how they work, keep reading.

After you've turned on two-step verification, some apps (like the mail apps on some phones)  or devices (like an Xbox or Windows Phone,(read kindle fire) for example) will show an incorrect password error, because they can't prompt you to enter a security code when you try to sign in.

If you've turned on two-step verification, and you see an incorrect password error with an app or device, you'll need to get and enter a unique app password to sign in. Once you've signed in with your app password, you're all set to use that app or device. You'll need to create and sign in with a new app password for each app or device that can't prompt you for a security code.

1. Sign in to your Microsoft account.

2. Under Password and security info, tap or click Edit security info.

3. If you're prompted for a security code here, enter it and tap or click Submit.

4. Under App passwords, tap or click Create a new app password.

5. A new app password is generated and appears on your screen.

I Hope it helps. Please reply for any further help.
