How to set up an iCloud+ custom domain in Outlook for Windows

Hi, fellas,

I’ve bought an iCloud+ custom domain through Cloudflare and successfully set it up on my iPhone, but I can’t get it to work with Outlook for Windows on my laptop. The app accepts my iCloud.com settings but not my custom domain. As a result, I can receive emails sent to my custom domain, but I can only send emails using my iCloud.com address. I’d like my outgoing emails to show my new custom domain as the sender, not my iCloud.com address.

How can I set up an iCloud+ custom domain in Outlook? The IMAP settings just don't work:

IMAP server: imap.mail.me.com @993

SMTP server: smtp.mail.me.com @587

SSL ON

User: Do I use the custom domain e-mail? Or the iCloud.com e-mail?

Are the IMAP and SMTP servers correct?
