Can I add custom subdomains or multiple domains to Office 365?

You can add multiple custom domains in all Office 365 subscriptions, but you can only add subdomains to Office 365 Midsize Business and Office 365 Enterprise. There are important differences for other domains features as well.

Compare the features side-by-side in the table below to make sure Office 365 Small Business will meet your needs before you add your domain. (The Office 365 domains service description includes an even more detailed list.) Otherwise, you could get part way through setting up your domain with Office 365 Small Business and find that you can’t do something important to your business, such as using subdomains. At that point, it’s time-consuming to remove your domain from Office 365 and switch to a different Office 365 offering.

 Note    As you're considering which Office 365 subscription is best for you, you might want to review the overall product features of each offering, to weigh those priorities along with your domains needs.

Subdomains

You can add a custom domain, such as contoso.com, but you can’t add subdomains, such as partners.contoso.com.

 Note    Office 365 Small Business automatically prepends “www” to your domain name if you use the domain with your Office 365 public website, like www.contoso.com. You don’t have to worry about not being able to add a “www” subdomain.

You can add multiple subdomains: for example, www.contoso.com, www.partners.contoso.com, www.partners.marketing.contoso.com, and so on.

Current public website If you choose to have Office 365 manage your DNS, follow the extra steps to keep using your current website instead of setting up a new one, to make sure people can get to the site after you add your domain. When you add your domain to Office 365, you can keep hosting your current website without doing anything further.
DNS records

After you set up your domain in Office 365, you have a choice. You can either have Office 365 create and host your DNS records and automatically configure your services, such as email and Lync, or you can manage your DNS records at your DNS hosting provider.

After you set up your domain in Office 365, you add and update your DNS records on your DNS hosting provider website and configure the DNS records for services, such as email and Lync.

You continue to manage your DNS records at your DNS hosting provider (or on premises, if you manage your own DNS file locally) - for example, to add or update MX or CNAME records.

Email and IM

If you choose to have Office 365 create and host your DNS records, email and IM are automatically set up to use your domain, hosted by Office 365, and you can’t host email or IM with another hosting provider.

If you choose to manage your own DNS records at your DNS hosting provider, you can host email or IM with another hosting provider.

You can set up email, IM, and your public website to use your domain hosted by Office 365, or you can host some (or all) of those services on your domain with another provider.
Multiple domains

You can add multiple domains to Office 365.

If you choose to have Office 365 create and host your DNS records you can set up Office 365 email and IM together on any of those domains.

If you choose to manage your own DNS records at your DNS hosting provider, you can host any of the services on any of the domains. For example, you could use email with one domain name and use another domain name for the address of your SharePoint Online public website.

For example, you could use email with one domain name and use another domain name for the address of your SharePoint Online public website.

Additional information about how domains work with Office 365 services

  • You can add up to 600 domains to your Office 365 account.
  • You can't import a public website to Office 365. So if you choose to use your domain with your Office 365 public website instead of keeping your current website, you have to design and populate the new website from scratch.
  • Office 365 creates a domain for you when you sign up with the service, like contoso.onmicrosoft.com. You can keep using this domain for your user ID and for your Office 365 services, or add your own custom domain.
  • You can use any custom domain name that is available at your domain name registrar. It doesn’t have to match the first part of your onmicrosoft.com domain. For example, if you signed up for Office 365 using fabrikam.onmicrosoft.com, you could use fabrikam.com, fabrikam_NW.com, or a completely different name like fourthcoffee.com.
