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.

1. To get started, go to your domains page at Active24 by using this link. You'll be prompted to Log In first.

   

2. On the Customer center page, in the Domain overview section, choose the name of the domain that you want to edit.

   

3. Under **Domain details: (domain_name, choose DNS administration.

   

4. On the Customer center page, in the Add record section, choose TXT.

   

5. In the boxes for the new record, type or copy and paste the values from the following table.

   Name	TTL	Text
   (Leave this field empty.)	3600	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.

   

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.

3. On the Setup page, choose Start setup.

   

4. On the Verify domain page, choose Verify.
