Create DNS records at E-business Services for Office 365

Caution: The E-business Services website doesn't support SRV records, which means that several Skype for Business Online and Outlook Web App features won’t work. No matter which Office 365 operated by 21Vianet plan you use, there are significant service limitations, and you may want to switch to a different DNS hosting provider.

If despite the service limitations, you choose to manage your own Office 365 DNS records at E-business Services, follow the steps in this article to verify your domain and set up DNS records for email, Lync, and so on.

These are the main records to add.

After you add these records at E-business Services, your domain will be set up to work with Office 365 services, though not with the Lync Online and Outlook Web App features mentioned above.

If you have a SharePoint Online Public Website, you can set it up to use your custom domain for the website URL address, like www.your_domain.com.

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.

Add a TXT record for verification

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.

  1. In your browser, go to E-business Services domain control panel and sign in with your domain name and password.

    Sign in to domain control panel

  2. Click DNS解析管理 (DNS record management).

    The DNS records page for your domain opens.

    Click "DNS解析管理"

  3. In the 高级解析 (advanced DNS settings) section, click 文本记录(TXT记录) (TXT record).

    Click "文本记录(TXT记录)"

  4. Make sure that the fields are set to precisely the following values for the empty record:

    • 主机名 (host name): Leave the box blank.

    • 内容 (value): Paste Destination or Points to Address value from the table in Office 365, for example MS=msXXXXXXX. How do I find this?

    Add TXT record

  5. Click 增加 (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 Domains page.

  2. On the Manage domains page, select the domain that you are verifying and then, in the Action column for that domain, 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.
