Greetings monem290,

If you are setting your iCloud Mail up on a non Apple device, you may need these settings: iCloud Mail server settings for other email client apps

Should we have an incorrect understanding of the issue, consider offering additional details to help the community guide you to a resolution.

1. What exactly is happening vs what you expect to happen?
2. Any error messages?
3. Which device and OS are you using?

We hope this helps!

Sincerely.
