Sign in to the Microsoft 365 admin center. Open Settings > Domains, add your domain and choose manual DNS configuration.
Copy the TXT value Microsoft displays for your domain. In the EDIS customer area, open the DNS editor under Domains. Add the required TXT record with that value. A value such as MS=ms987654321 is only an example.
Start verification at Microsoft. If the record is not found yet, wait and try again.
Copy the DNS records for your chosen services exactly from the Microsoft wizard. Do not use someone else’s example IP addresses. Set up all required Microsoft mailboxes before changing the MX record. The MX change moves incoming email to Microsoft.
