How to Connect a Microsoft-Registered Domain to an External Website
Product
Microsoft 365
Device & OS
not provided
Scenario
Configuring DNS records to link a Microsoft-managed domain with an external website hosting service.
Observed behavior
The domain requires correct DNS record configurations in the Microsoft 365 admin portal to successfully resolve to the external hosting provider's server.
Before you start

Ensure you have administrator access to your Microsoft 365 account and have obtained the specific DNS records (such as the static IP address for an A record) from your external website hosting provider.

Solution 1Recommended

Update DNS Records in the Microsoft 365 Admin Center

Create or modify the A record in your Microsoft 365 DNS settings to point your domain to the static IP address of your external website host.

To connect your domain to an external host, you must direct the domain's web traffic to the host's servers. This is typically done by adding an A record. If your hosting provider uses dynamic IP addresses, they may provide a CNAME record or custom nameservers instead.

1
Log in to the Admin Center

Sign in to the Microsoft 365 Admin Center with your administrator credentials and navigate to the 'Settings' menu on the left sidebar, then click on 'Domains'.

2
Select your domain

Click on the specific domain name you want to connect to your external website, and select the 'DNS records' tab to view your current configuration.

3
Add a new DNS record

Click the 'Add record' button. Choose 'A record' from the type dropdown menu (or the specific record type recommended by your hosting provider).

4
Enter hosting provider details

Input the static IP address provided by your external website host into the designated value field. Leave the TTL at the default setting unless instructed otherwise, and click 'Save'.

Frequently Asked Questions

How long will it take for my external website to appear after changing Microsoft domain settings?

It typically takes between 1 to 48 hours for DNS changes to propagate globally. If your website is still not loading after 48 hours, verify that the IP address you entered in the Microsoft 365 Admin Center matches exactly with the one provided by your host.

Should I use an A record or change my Nameservers (NS)?

You should use an A record if you want to point your website to an external host while keeping your email and other services managed by Microsoft 365. Changing Nameservers (NS) transfers all DNS management (including email routing) to the external hosting provider, which requires you to set up MX records on their end to keep your Microsoft email working.

What if my external hosting provider does not offer a static IP address?

If your external provider uses changing (dynamic) IP addresses, they will typically ask you to configure a CNAME record instead of an A record, or they will provide specific custom nameserver instructions for you to input into your Microsoft 365 domain settings.
