Managing Your Domain

Managing Your Domain

If you have purchased a domain and want your email address to use the name of your organization (for example, PowerObjects would want for the end of the email address), you can use your custom domain in the Microsoft Portal. When activating your Office 365 or Dynamics 365 Online account, you will enter your company’s domain name. Once your account is activated, your domain will have ( at the end of it. Follow these steps to verify your domain:

1. In the Admin Center in the Microsoft Online Portal scroll down and find the box called Domains, then click Add a domain.

2. Follow the three steps Microsoft lays out for you to add your domain:

  1. Specify a domain name and confirm ownership. Before you can use your custom domain with Office 365, Microsoft needs you to confirm that you own it. You can only add domain names that you own. If you don’t already own a domain, you can buy one from a domain registrar, and then come back and add it to Office 365.
  2. Add users and assign licenses. Create users and email addresses for this domain.
  3. Set the domain purpose and configure DNS. Choose how you want to use this domain with Office 365 and create DNS records

Before you set up your domain with Office 365, Microsoft has to make sure that you own the domain name. To do that, you’ll add a specific record to the DNS records at your DNS hosting provider. Microsoft then looks for the record to confirm ownership.

When adding your DNS records to your DNS hosting provider, Microsoft does provide step-by-step instructions on adding DNS records. Select the drop-down option and choose your DNS provider. If your DNS provider is not listed, you can select General Instructions.

Managing Your Office 365 Domain

Tip! Your TXT records will verify your domain, and your MX records will switch where your emails are being delivered to. If you are not moving your email system to Office 365, you don’t want to switch the MX records.


If you are having issues after changing your domain name or DNS records, there are additional steps you can take to complete setting up your domain. For more information on the additional steps you can take if your domain is troubleshooting visit, Office 365 Admin Help.
