On the next page, choose Done, verify now and then, in the confirmation dialog box, choose Finish.

Change your domain’s name server records

When you get to the last step of the wizard, you have one task remaining. To complete setting up your domain with Office 365, you change your domain’s NS records at your domain registrar to point to the Office 365 primary and secondary name servers. Then, because Office 365 hosts your DNS, we can set up the required records for you so that email, Lync, and your public website work with your domain.
Caution    When you change your domain’s NS records to point to the Office 365 name servers, all the services that are currently associated with your domain are affected. If you skipped any steps of the wizard, or if you’re using your domain for blogs, shopping carts, or other services, there are additional steps that are required to make sure that this transition doesn't result in service downtime, such as loss of email access or your current website being inaccessible.
For example, here are some additional steps that might be required for email and website hosting:

1. Move all email addresses that use your domain to Office 365 before you change your NS records. Learn more: Why should I add users to Office 365 while I'm adding my domain?
   
2. Adding an additional domain? You can take steps while you add the domain to keep its website hosted where the site is hosted now.
   
3. If you have a website already, you can choose to keep your website with your current hosting provider.
   

In the last step of the wizard, use the steps in the following table to change your domain’s name servers at your domain registrar.

Task	Action
Go to the area on your domain registrar’s website where you can edit name server records.	On the Yahoo! Small Business website, choose manage DNS settings. For more information, see Find your DNS records at Yahoo! Small Business. Scroll down to the Name Servers section.
Change your name server records to point to the Office 365 name servers.	Choose Change Nameservers. In the Primary row, in the Nameserver Hostname column, type or paste the following value: ns1.bdm.microsoftonline.com In the Secondary row, in the Nameserver Hostname column, type or paste the following value: ns1.bdm.microsoftonline.com Tip   You should use at least two name server records. If there are any other name servers listed, you can either delete them, or change them to ns3.bdm.microsoftonline.com and ns4.bdm.microsoftonline.com. If there are any other name servers specified, and you want to delete them, select the text in the Nameserver Hostname column, and then press the Delete key.
Save your changes.	Choose Submit.
If you’re done making DNS changes, lock your domain.	Choose Domain Control Panel. Choose Edit Domain Locking. Choose Lock Domain. In the confirmation page, choose Lock Domain again.

Your name server record updates may take up to 72 hours to update through the DNS system. Your custom domain will be ready to use with Office 365 after the updates complete.
