Change nameservers to set up Office 365 with Register365

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 Register365.)

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 Register365 by using this link. You'll be prompted to log in first.

    Register365-BP-Configure-1-1

  2. O365_DOM_Register365_Login2_ChooseDomain
  3. On the Add/Modify DNS Zone page, in the A, CNAME, AAAA, TXT and NS records section, in the boxes for the new record, type or copy and paste the values from the following table.

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

    (If you need to add a row, choose ADD A/CNAME RECORDS (+).)

    (You may have to scroll down.)

    Host name

    Type

    Result

    (Leave this field empty.)

    TXT

    MS=msXXXXXXXX

    O365_DOM_UseDestinationPointsToAddressFromTable

    Register365-BP-Verify-1-1

  4. Choose Save.

    (You may have to scroll down.)

    Register365-BP-Verify-1-2

  5. O365_DOM_WaitForUpdateAcrossInternet

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?

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 Register365 by using this link. You'll be prompted to log in first.

    Register365-BP-Configure-1-1

  2. On the Dashboard page, find the name of the domain that you're updating, and then choose DNS Settings from the drop-down list.

    Register365-BP-Configure-1-2

  3. On the Summary Info page, under Domain Names, choose DNS & Transfer Options.

    Register365-BP-Redelegate-1-2

  4. Under DNS & Transfer Options, choose Change Nameservers.

    Register365-BP-Redelegate-1-3

  5. Depending on whether or not there are already nameservers listed on the page that is displayed now, continue to one of the two following procedures:

If there are NO nameservers already listed

  1. In the first two boxes in the New nameservers area, type or copy and paste the values from the following table.

    First nameserver

    ns1.bdm.microsoftonline.com

    Second nameserver

    ns2.bdm.microsoftonline.com

    Third nameserver

    ns3.bdm.microsoftonline.com

    Second nameserver

    ns4.bdm.microsoftonline.com

    Register365-BP-Redelegate-1-4

  2. Choose UPDATE.

    Register365-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.

If there ARE nameservers already listed

Caution: Follow these steps only if you have existing nameservers other than the four correct nameservers. (That is, delete only any current nameservers that are not named ns1.bdm.microsoftonline.com, ns2.bdm.microsoftonline.com, ns3.bdm.microsoftonline.com, or ns4.bdm.microsoftonline.com.)

  1. If there are any other name servers listed in the New nameservers area, delete each of them by selecting it and then pressing the Delete key on your keyboard.

    Register365-BP-Redelegate-1-6

  2. Still in the New nameservers area, type or copy and paste the values from the following table into the first two boxes.

    First nameserver

    ns1.bdm.microsoftonline.com

    Second nameserver

    ns2.bdm.microsoftonline.com

    Third nameserver

    ns3.bdm.microsoftonline.com

    Fourth nameserver

    ns4.bdm.microsoftonline.com

    Register365-BP-Redelegate-1-4

  3. Choose UPDATE.

    Register365-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.
