Add records at any DNS hosting provider to set up your SharePoint Online Public Website

Note: The SharePoint Online Public Website information in this article only applies if your organization purchased Office 365 prior to March 9, 2015.

Before you rename the site to use your custom domain name, make sure you've finished designing the website (in Office 365) and that you're ready for everyone to see it. Then when you're ready to use your custom domain for the address, you create (at the DNS host for your domain) a CNAME record to point to your customized website.

Ready to create that CNAME record at your DNS hosting provider? Follow the steps in this article. (Need more help? Get support.)

Add the CNAME record to use your custom domain

First, review one of the two following linked articles (depending on the Office 365 subscription you have) for an overview of the process.

Then, when you’re ready to create the required CNAME record, use the steps in the following table.



Gather information from SharePoint Online.

  1. From the Manage domains page in Office 365, go to the SharePoint admin center:

    1. Choose Domains, choose the domain name, and then choose Edit domain intent.

    2. Choose SharePoint Online.

    3. Choose Save.

    4. Choose SharePoint admin center.

  2. From the SharePoint admin center:

    1. Choose Manage site collections, and then select the check box next to your public website.

    2. On the ribbon, choose DNS Information.

  3. Write down or copy the target address so you’ll have it ready for the next step, Add a CNAME record.

Add a CNAME record.

  1. At your DNS hosting provider, add a CNAME record.

  2. Add the required information in the empty record:

    • Map the name of your custom domain; for example, to where name is the name of your custom domain; for example,

  3. Save the record.

Note:  Typically it takes about 15 minutes for DNS changes to take effect. However, it can occasionally take longer for a change you've made to update across the Internet's DNS system. If you’re having trouble with mail flow or other issues after adding DNS records, see Troubleshoot issues after changing your domain name or DNS records.
