How to Move DNS MX Records for Microsoft 365 Email During Domain Transfer
Question details
The user needs to transfer their domain and MX records to a new hosting provider without disrupting Microsoft 365 email services, while also regaining administrative access to manage accounts.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Transferring domain and DNS MX records to a new hosting provider.
- Observed behavior
- The organization has active email accounts but currently lacks administrative access to manage or create new accounts, and needs to ensure complex email routing continues working after the domain transfer.
Before changing your DNS settings, ensure you have the correct Microsoft 365 MX record values (usually ending in .mail.protection.outlook.com) and access to your new domain registrar's DNS management console.
Update DNS MX Records at Your New Hosting Provider
Manually configure your new host's DNS settings to point to Microsoft 365 to ensure uninterrupted email delivery.
When transferring a domain to a new provider, MX records do not migrate automatically. You must manually add the Microsoft 365 DNS values at the new host to keep your email functional.
Log in to your new domain hosting provider's control panel and navigate to the DNS Management or DNS Zone Editor section.
Create a new MX record and input your specific Microsoft 365 MX value (e.g., yourdomain-com.mail.protection.outlook.com) with the correct priority (usually 0).
Save the changes and wait for DNS propagation, which can take anywhere from a few minutes to 48 hours.
Log in to the Microsoft 365 Admin Center (once access is restored) to verify domain ownership and confirm the DNS status is healthy.
Restore Microsoft 365 Administrative Access
Contact Microsoft Support if no user in your organization can access the admin center to manage emails.

Frequently Asked Questions
Why did my Microsoft 365 email stop working after a domain transfer?
When a domain is transferred to a new registrar or host, DNS records like MX (Mail Exchanger) do not always carry over automatically. You must manually add your Microsoft 365 MX records to the new host's DNS settings.
How do I find my Microsoft 365 MX record value?
You can find your specific MX record value in the Microsoft 365 Admin Center under Settings > Domains. Select your domain to view the required DNS records for email routing.
How long does it take for MX record changes to take effect?
DNS propagation typically takes anywhere from a few minutes to 48 hours. During this time, email delivery might fluctuate depending on the geographical location of the sender.
What should I do if my MX routing includes both Google and Microsoft?
If you have a split-delivery or dual-routing setup, ensure you meticulously copy all existing MX records and their respective priorities from your old DNS host to the new one to maintain the current mail flow.
