Change nameservers to set up Office 365 with Active24

Contributors: Peter Baumgartner

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

Follow these instructions if you want Office 365 to manage your Office 365 DNS records for you. (If you prefer, you can manage all your Office 365 DNS records at Active24.)

Here’s what you need to do. (Need more help? Get support.)

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

    Active24-BP-Configure-1-1

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

    Active24-BP-Configure-1-2

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

    Active24-BP-Configure-1-3

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

    Active24-BP-Verify-1-1

  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=msXXXXXXXX

    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?

    Active24-BP-Verify-1-2

  6. Choose Create.

    Active24-BP-Verify-1-3

  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. Go to the Domains page.

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

    O365-BP-Verify-1-2

  3. On the Setup page, choose Start setup.

    O365-BP-Verify-1-3

  4. On the Verify domain page, choose Verify.

    O365-BP-Verify-1-4

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. If you’re having trouble with mail flow or other issues after adding DNS records, see Troubleshoot issues after changing your domain name or DNS records.

Change your domain’s nameserver (NS) 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 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, Skype for Business Online, 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.

Important: 

  • When you have completed the steps in this section, the only nameservers that should be listed are these four:

  • The following procedure will show you how to delete any other, unwanted nameservers from the list, and also how to add the correct nameservers if they are not already in the list.

  • ns1.bdm.microsoftonline.com

  • ns2.bdm.microsoftonline.com

  • ns3.bdm.microsoftonline.com

  • ns4.bdm.microsoftonline.com

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

    Active24-BP-Configure-1-1

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

    Active24-BP-Configure-1-2

  3. Under Domain details:domain_name, choose Change of nameservers.

    Active24-BP-Redelegate-1-1

  4. In the Nameservers section, choose change.

    (You may have to scroll down.)

    Active24-BP-Redelegate-1-2

  5. In the Nameservers section, delete each nameserver by selecting it and then pressing the Delete key on your keyboard. Next, delete each Ipv4 value by selecting it and then pressing the Delete key on your keyboard.

    (You may have to scroll down.)

    Active24-BP-Redelegate-1-3

  6. Still in the Nameservers section, in the Nameserver1 to Nameserver4 boxes, type or copy and paste the values from the following table.

    Nameservers

    Hostame

    Ipv4

    Nameserver1

    ns1.bdm.microsoftonline.com

    (Leave this field empty.)

    Nameserver2

    ns2.bdm.microsoftonline.com

    (Leave this field empty.)

    Nameserver3

    ns3.bdm.microsoftonline.com

    (Leave this field empty.)

    Nameserver4

    ns4.bdm.microsoftonline.com

    (Leave this field empty.)

    Active24-BP-Redelegate-1-4

  7. Choose Save.

    Active24-BP-Redelegate-1-5

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.
