Add a company domain

Know which domain you’ll be using for Yammer Enterprise? Whether you’re upgrading an existing Basic network or creating a new one, the first step is verifying your company domain on your Office 365 account. This allows us to securely connect and sync your services.

Yammer requires a company domain, such as, to activate the network. This means the default domain ( you created with your Office 365 account can’t be used to activate Yammer Enterprise.

Before you begin
  • You need to have access to your DNS hosting provider or domain registrar. If you don’t know how to do this, contact your company’s IT support for assistance.

  • Does your organization already have a Yammer network? Add that domain to Office 365 to upgrade the network to Enterprise.

  • If your organization has multiple company domains, activate Yammer using the one that hosts the majority of your employees, and add additional domains post-activation.

  • If your organization is using SharePoint sites, be sure to activate Yammer on a different domain. For example, if your SharePoint site is on, activate Yammer using the domain.

To add your company domain to Office 365
  1. Go to the Manage domains page. (If you're not already signed in to Office 365, you'll be prompted to sign in. If the link doesn't work, here are steps to navigate to the Manage domains page.)

    Click Domains on Office 365 Admin page
  2. Choose Add domain to start the setup wizard, which guides you through verifying your domain and other setup steps.

    Click Add domain on Office 365 Domains page
  3. Type your domain name in the setup wizard.

    Tip    If you don’t have a company domain, you can purchase one from a domain name registrar on the Domains page.

    Type the domain you want to use in Office 365
  4. Add the customized DNS record so Office 365 can confirm you own the domain. Office 365 typically detects your domain's DNS host, and provides step-by-step instructions for adding the record.

    In Office 365 click Step-by-step instructions for more info about adding TXT records
  5. When you've added the record at your DNS host, finish this step by choosing Okay, I've added the record.

  6. Define how you’ll use your domain by selecting Yammer or a combination with other Office 365 services, like Exchange Online or Lync Online.

  7. Update your DNS records using the provided Record Type details at your hosting provider or domain registrar to verify these services for Office 365.

    • Let Office 365 set up your DNS records for you (simplest). Change your domain's nameserver (NS) records at your domain registrar to point to Office 365 nameservers. The setup wizard typically detects your registrar, and gives you a link to step-by-step instructions for updating your NS records at the registrar website. Or you can follow these general steps for changing NS records. Then Office 365 can automatically set up email and other services for you.

      This changes your domain's DNS hosting to Office 365, so we don't recommend it if you have a website with your domain.

      In Office 365 click Step-by-step instructions for more info


    • Edit your domain's DNS records for Office 365 yourself. Go to your DNS host website, and set up the records yourself. The setup wizard typically detects your DNS host, and gives you a link to step-by-step instructions for updating records at their website. Or you can follow these general steps for updating records for Office 365.

      Add the following DNS records
  8. If this domain is your organization’s primary domain, change your default Office 365 domain from to the company domain you just added. Go to Admin > Office 365, click your organization name in the upper-right corner, and then choose Default domain.
