Change nameservers to set up Office 365 with Blacknight

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 Blacknight.)

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.

Follow the steps below.

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

    Blacknight-BP-Configure-1-1

  2. In the Domains section, choose Registered Domains.

    Blacknight-BP-Configure-1-2

  3. Under Registered Domains, find the name of the domain that you want to edit and then, in that same row, choose Manage DNS.

    Blacknight-BP-Configure-1-3

  4. Choose the DNS tab.

    Blacknight-BP-Configure-1-4-1

  5. Then choose DNS Records.

    Blacknight-BP-Configure-1-4-2

  6. Choose Add New DNS Record.

    Blacknight-BP-Configure-1-5

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

    (Select the DNS Record Type value from the drop-down list.)

    DNS Record Type

    Domain

    Data

    TTL

    TXT

    (Leave this field empty.)

    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?

    Select Custom and enter the value 3600.

    Blacknight-BP-Verify-1-1

  8. Choose Finish.

    Blacknight-BP-Verify-1-2

  9. 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 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

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?

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

  • ns1.bdm.microsoftonline.com

  • ns2.bdm.microsoftonline.com

  • ns3.bdm.microsoftonline.com

  • ns4.bdm.microsoftonline.com

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.

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

    Blacknight-BP-Configure-1-1

  2. In the Domains section, choose Registered Domains.

    Blacknight-BP-Configure-1-2

  3. Under Registered Domains, locate the domain that you want to edit, and then choose domain_name.

    Blacknight-BP-Redelegate-1-1

  4. On the Name Servers section, choose Manage Nameservers.

    Blacknight-BP-Redelegate-1-2

  5. In the Domain Name Servers section, delete each nameserver by selecting it and then pressing the Delete key on your keyboard.

    Blacknight-BP-Redelegate-1-3

  6. Still in the Domain Name Servers section, in the Primary Name Server and Secondary Name Server boxes, type or copy and paste the values from the following table.

    Primary Name Server

    ns1.bdm.microsoftonline.com

    Secondary Name Server

    ns2.bdm.microsoftonline.com

    Blacknight-BP-Redelegate-1-4

  7. Choose Update Name Server.

    Blacknight-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.
