Office 365 for professionals and small businesses provides a domain name that you use when you create a public website with the service, but you can use your own custom domain name instead if you like.
For example, instead of using contoso.sharepoint.com – your original Office 365 SharePoint domain – you’ll be able to use simply contoso.com.
There are a lot of benefits to using a domain name that you’ve purchased for your business. For example, it looks professional to have your own domain name, which makes your small business look like a bigger force in the market. And it makes it easier for customers to find your information, because they are more likely to be able to remember or guess the URL for your website.
To use your domain name with Office 365, you do the following:
- If you haven’t done so already, add your custom domain to Office 365. For more information, see Add your domain to Office 365.
- Customize your Office 365 public-facing website by adding your company name, logo, and business information. For more information, see Customize a public-facing website.
- On the Admin page, in the left pane, under Management, click Domains.
- Click Change address, and then step through the wizard.
Tip If you want to keep your current public-facing website, hosted outside of Office 365, instead of creating a new public website that uses your domain on Microsoft SharePoint Online, don’t use the Change address option to point traffic to your SharePoint Online website. Instead, redirect your website traffic from Office 365 back to the hosting provider where your website is located. To learn how, see Update DNS records to keep your website with your current hosting provider.
