Create DNS records at East.net for Office 365

If east.net is your DNS hosting provider, 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 east.net, your domain will be set up to work with Office 365 services.

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 your domains list at east.net and sign in.

    Sign in to east.net

  2. In the right pane, in the 操作 (actions) column for the domain that you want to update, click 域名管理 (domain management).

    Click "域名管理" (domain management) for your domain

  3. Click the 域名解析 (domain name resolution) tab.

    The DNS records page for your domain opens.

    Click "域名解析" (domain name resolution)

  4. In the 新增解析记录 (add a DNS record) section, 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

    • 类型 (type): TXT

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

    Select "TXT"

  5. Click 新增 (add).

    Add TXT record

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.

    O365-BP-Verify-1-3

  4. Choose Next.

    O365-BP-Verify-1-4
