Check the Domains FAQ if you don't find what you're looking for.

If Dyn.com is your DNS hosting provider, follow the steps in this article to verify your domain and set up DNS records for email, Skype for Business Online, and so on.

To learn about webhosting and DNS for websites with Office 365, see Use a public website with Office 365.

Add a TXT record for verification

1. To get started, go to your domains page at Dyn.com by using this link. You'll be prompted to login first.

   

2. On the Zone Level Services page, choose Dyn Standard DNS Service for the domain that you want to edit.

3. On the DNS page for your domain, choose Preferences.

4. Choose Enable Expert Interface.

5. In the Add DNS Record section, in the boxes for the new record, type or copy and paste the values from the following table.

   (Choose the Type value from the drop-down list.)

   Host	TTL	Type	Data
   (Leave this field empty.)	600	TXT	MS=ms XXXXXXXX Note: This is an example. Use your specific Destination or Points to Address value here, from the table in Office 365. How do I find this?

   

6. Choose Create Record.

   

7. Wait a few minutes before you continue, so that the record you just created can update across the Internet.

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. Choose Setup > Domains.

2. On the Domains page, choose the domain that you are verifying.

   

3. On the Setup page, choose Start setup.

   

4. On the Verify domain page, choose Verify.

1. To get started, go to your domains page at Dyn.com by using this link. You'll be prompted to login first.

Add it to the beginning of the MX value, separated from the remainder of the value by a space. Note: Get your <domain-key> from your Office 365 portal account. How do I find this? For more information about priority, see What is MX priority?

   

6. Choose Create Record.

   

7. If there are any other MX records, remove them by selecting the check box for each one in the Delete column.
