Add records at IDC1 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 Office 365 operated by 21Vianet website 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 IDC1? Follow the steps in this article.

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.

• If you're using Office 365 Small Business, get an overview of the process by reading Use a custom domain name to rename your Office 365 public website.

• If you have any other subscription of Office 365, review the instructions in Rename your SharePoint Online Public Website address to use your custom domain.

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

Task

What you'll see

Add a CNAME record. On the IDC1 website, open the DNS records page for your domain. To find the DNS records page for your domain, see Find your DNS records at IDC1. On the 新建子域名 (add new subdomain) tab, in the 指向类型 (record type) drop-down list, select CNAME/别名 (CNAME/alias). Make sure that the fields are set to precisely the following values for the empty record: 子域名 (subdomain): Use the name of your custom subdomain; for example, www. 域名 (points to domain): Use name.sharepoint.cn, where name is the first part of your initial partner.onmschina.cn domain; for example, contoso in contoso.partner.onmschina.cn. TTL: 3600 Click 增加 (add). Click 重启EDNS服务器 (restart EDNS server) for the changes to take effect across the Internet.

Set up redirection so that people can get to your public website if they don't type www

You probably want people to be able to get to your public website without including www in the address. To do this, use the steps in the following table to set up redirection at IDC1. This maps the root domain name, for example, http://fourthcoffee.com, to the full domain name, for example http://www.fourthcoffee.com.

For more information about redirection, see How can I make sure people can get to my Office 365 public website if they don't type www?

Notes: 

• If you select cloaked URL forwarding, the browser's address bar will retain the original URL after the URL redirects you to the destination URL. If you select uncloaked URL forwarding, the browser's address bar will display the destination URL after the original URL redirects you to the destination URL.

• After you enter your redirection information on the IDC1 website, you need to contact IDC1, and IDC1 will review and censor before they activate the redirection.

Task	What you'll see
Get an ICP number. Before setting up redirection, you need to get an Internet Content Provider (ICP) number for your domain.
Set up redirection. On the IDC1 website, open the DNS records page for your domain. To find the DNS records page for your domain, see Find your DNS records at IDC1. On the 新建子域名 (add new subdomain) tab, in the 指向类型 (record type) drop-down list, select URL 转发 (URL forwarding). Make sure that the fields are set to precisely the following values for the empty record: 子域名 (subdomain): Leave the box blank. 转发是否隐含 (cloak or not): Select 不隐含 (uncloak) or 隐含 (cloack). 网址 (destination URL): Type or paste your fully qualified URL; for example, http://www.fourthcoffee.com.
