Change how DNS records are managed with Office 365

If you change your mind about how you want DNS records to be managed for your domain in Office 365 operated by 21Vianet, you can switch to a different option after your domain is already set up. For example, if DNS for your domain is managed by Office 365, you can change it so you manage the DNS yourself, at your DNS host.

Making this change doesn't affect email for your domain or other Office 365 services.

Follow the steps provided here to:

Change DNS management to a DNS host outside Office 365

To switch DNS management, you must first change the nameservers for the domain to point to your DNS host. The nameservers for a domain determine where DNS is managed for the domain. They must be reset to your DNS host so that Office 365 can check that your DNS records for Office 365 are set up correctly at the DNS host after you switch DNS management.

After you change the nameservers, you follow a link that we provide to go to the domains setup wizard in Office 365, where you first set up your domain. In the wizard, you choose the option to manage your domain's DNS yourself, and then set up the DNS records for Office 365 services.

  1. Sign in to the domain registrar for your domain. How can I find my domain's registrar?

  2. Find the area on the registrar's website where you update nameserver records, and update the nameservers to point to your domain's DNS host. (The DNS host is often the domain registrar.)

More about DNS management options in Office 365

When you add your domain to Office 365, the domains setup wizard guides you to set up your domain's DNS management in one of two ways.

You can let Office 365 manage DNS records for the domain, to make it easier to set up services like email and Lync. This is the best option if you have a public website you're using with your domain outside of Office 365. Or you can keep managing the DNS records for your domain where they are now, at your current DNS host or domain registrar. There are advantages to each option, so you can pick the one that works best for your situation.

Later, if your situation changes, you can switch to the other option for DNS management by following the steps above.
