Hi jazib838,

Thanks for posting your email question to the Apple Support Communities. It appears that you're unable to send and receive email, so we'd like to help. Start by making sure your mail server settings are correct. Here's how: Mail server settings for iCloud email clients. There's some additional information you may find helpful here: If you can’t add iCloud Calendars, Mail, or Contacts to Outlook.

Cheers!
