Adding and Verifying a Domain for the NEW Office 365

After you have finished Signing up for the NEW Office 365, you are issued a Microsoft Office 365 Tenant account. From this account, you will want to add your public domain. This will allow Microsoft to host the desired Office 365 services for you and will allow you to use you own domain, rather than the tenant domain account (@domain.onmicrosoft.com) default account.

The process should be quite easy and painless as long as you have access to the Microsoft Online Portal, with a Global Admin account, and access to your public facing DNS.

 

  1. Open Internet Explorer

     

  2.  

  3. Click Domains

     

  4. Click Add a Domain

     

  5. Click Start Step 1

     

  6. Enter your public domain name and click Next

     

  7. Domain verification needs to be completed by adding a TXT or MX record into your public facing DNS. This is critical to verify ownership of the domain. In most cases the safest and method is to add the TXT record.

     

  8. Login to your public DNS provider and enter the TXT record specified by Microsoft. I choose to use GoDaddy as I find they are a one stop shop for domains, DNS, hosting, certificates and the kitchen sink.

     

  9. After the TXT record has been added you can go back to the Office 365 Portal site. Click the Done, verify now button

     

     

  10. Once the domain is verified, click Finish

     

  11. Click Start Step 2

     

  12. At this point you have the option to add user accounts. Depending on what your plans are, you can add them manually, with a CSV file or at a later date. For this post, I elected to not add any users at this time.

     

  13. Click Next

     

  14. Click Start Step 3

     

  15. We have to set the purpose of the domain. For this post, we are going to select Exchange Online and Lync Online. This is the default configuration and the most common. I am also going to leave the on-premise mailbox option unchecked at this point as well. We can change this later.

     

  16. Click Next

     

  17. At this point we are supplied a list of DNS records that will have to be added for the Office 365 Services to work. Depending on your DNS setup (split brain); these will have to be entered into your public and private DNS.

     

    WARNING – If you are in a production state, changing the DNS records will affect service. Plan accordingly. Depending on your situation, you can add all the records except the MX record. This is usually changed after the migration is completed.

     

  18. For my example, I am in non-production and I have entered all DNS records as provided by Microsoft.

     

    After all (or the ones that you want to add now) are added, give it sometime to update

     

  19. Click Done, go check

     

  20. Your DNS records will be verified

     

  21. Click Finish

     

  22. You will now see the domain is added and Active

     

 

At this point your domain is added and active with in Office 365.

    A useful addition to your series would be setting up an Internal Relay system, where the MX and some mailboxes will stay with the POP3 provider, but some mailboxes will be on O365

    Cheers

      I have a POP3 migration series, where email is in both POP3 and Exchange. It gets complicated for the average admin, because of the mail routing and vanity domains.
