Change nameservers to set up Office 365 at CNDNS

Follow these instructions if you want Office 365 operated by 21Vianet to manage your Office 365 DNS records for you. (If you prefer, you can manage all your DNS records at CNDNS.)

Here’s what you need to do:

Add a TXT record to verify that you own the domain

Before you use your domain with Office 365, we have to make sure that you own it. Your ability to log in to your account at your domain registrar and create the DNS record proves to Office 365 that you own the domain.

Note:  This record is used only to verify that you own your domain; it doesn’t affect anything else. You can delete it later, if you like.

Follow the steps below.

  1. In your browser, go to your domains list at CNDNS and sign in.

    Sign in to CNDNS

  2. In the 操作 (actions) column for the domain that you want to update, click 解析 (domain name resolution).

    The DNS records page for your domain opens.

    Click "解析"

  3. In the 域名解析记录列表 (DNS record list) section, make sure that the fields are set to precisely the following values for the empty record:

    • 主机名 (host name): @

    • 记录类型 (record type): TXT记录 (TXT record)

    • 记录值 (value): Paste Destination or Points to Address value that you just copied.

    Add TXT record

  4. Click 立即添加 (add).

Now that you've added the record at your domain registrar's site, you'll go back to Office 365 and request Office 365 to look for the record.

When Office 365 finds the correct TXT record, your domain is verified.

  1. Go to the Manage domains page.

  2. On the Manage domains page, in the Action column for the domain you are verifying, choose Start setup.

    O365-BP-Verify-1-2

  3. On the Add this TXT record to show you own domain_name page, choose Okay, I've added the record and then, in the confirmation dialog box, choose Finish.

    O365-BP-Verify-1-3

Change your domain’s nameserver records

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 operated by 21Vianet primary and secondary name servers. This sets up Office 365 to update the domain's DNS records for you. We'll add all records so that email, Lync, and your public website work with your domain, and you'll be all set.

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. For example, all email sent to your domain (like rob@your_domain.com) will start coming to Office 365 after you make this change.

Ready to change your NS records so Office 365 can set up your domain? Follow the steps below.

  1. In your browser, go to your domains list at CNDNS and sign in.

    Sign in to CNDNS

  2. In the 操作 (actions) column for the domain that you want to update, click 管理 (manage).

    Click "管理"

  3. Click the 修改DNS (change name servers) tab.

    Click "修改域名DNS"

  4. In the DNS1 row, type or paste ns1.dns.partner.microsoftonline.cn.

    Change name servers

  5. In the DNS2 row, type or paste ns2.dns.partner.microsoftonline.cn.

  6. Click 确定 (OK).

Note: Your nameserver record updates may take up to several hours to update across the Internet's DNS system. Then your Office 365 email and other services will be all set to work with your domain.
