Hello Movie Boom,
I understand that you are having an issue with connecting to your iCloud email. While I know it can be frustrating, it is something that can be fixed.
Start by taking a look at the article below. It will have details on checking the settings for your email as well additional troubleshooting if nothing in the article resolves the issue. I have quoted a section for checking your settings as well so you do not have to hunt that part down.
Get help using iCloud Mail
https://support.apple.com/en-us/HT203528
Find the name of your iCloud account on the left side of the main Mail window. If your account name is dimmed and has a lightning-bolt symbol next to it, your account is offline. To take your account online, connect to the Internet, then choose Mailbox > Take All Accounts Online. If you still need help, use these steps:
- Choose Mail > Preferences.
- Click the Accounts tab.
- Select your iCloud account from the list of accounts.
- Click the Advanced tab and check your settings:
- Port: 993
- Select Use SSL
- Authentication: Password or Apple Token
Let me know if this helps you are or are still having the same issue.
Take care
