Problem turning on iCloud mail

Hi MEGA49R, 

Thank you for posting to the Apple Support Communities. 

Please start with these instructions If iCloud Mail isn't working. If you are setting up a new Apple ID or iCloud account, be sure to follow these instructions: How to create a new Apple ID. If available, you can set up the account with a second device before signing in on your iPhone.

Please reply back if you need more help with this.

Have a great day!

Hey MEGA49R,

Sometimes when you get a message to “try again later”, it can mean you’re having problems connecting to the Apple ID/iCloud ID server. These steps can help: If you can't connect to the App Store, iTunes Store, or other Apple services - Apple Support

Add and manage email aliases for iCloud Mail on iCloud.com - Apple Support -- If you’re trying to add or manage an email alias for iCloud Mail, please contact Apple Support to look into this further with you: Get Support

All the best.
