Assistance Needed for Email Configuration with iCloud+ and Cloudflare Domain


I hope this message finds you well. I am reaching out for assistance with configuring email using my custom domain subscribed via Cloudflare and configured through iCloud+. My goal is to set up my iCloud+ email account on an Outlook client, but I am encountering configuration issues.

Here are the details of my current situation:

  • Custom Domain: **** (Owned and Configured through Cloudflare)
  • Email Provider: iCloud+ (xxx@****)
  • Email Client: Microsoft Outlook

I have successfully added the required MX ( / and CNAME (sig1.dkim.**** records in my DNS settings via Cloudflare, as indicated in the configuration guides. Additionally, I have completed the domain ownership verification process with iCloud+.

However, when I attempt to configure my email account in Outlook using my custom email address (xxx@****), I receive error messages stating that Outlook cannot connect to the mail server.

I have double-checked the mail server settings (IMAP, SMTP, etc.) provided by iCloud+ for my custom domain, which is configured through Cloudflare. Despite these efforts, I am still unable to establish a successful connection.

I kindly request your expert assistance in resolving this issue and properly setting up my email account in Outlook using my custom domain, which is managed via Cloudflare and configured with iCloud+. I would greatly appreciate it if you could provide me with specific steps to follow or any additional information that could help me address this situation.

Thank you in advance for your help. I am available to provide any further information if needed.

Best regards,
