  • DNS managed by GoDaddy
  • has configured with Azure Exchange for emails. (via MX record on GoDaddy)
  • configured to Hostinger email server (via MX record on GoDaddy)

at this point the address on was receiving emails successfully.

after adding to "Microsoft Entra ID -> Custom domain names" the addresses on stop receiving emails from Microsoft emails but it's receiving email successfully from other email provider like Gmail.

the error message is: Your message to couldn't be delivered. reem wasn't found at

before adding to "Custom domain names"
