If you have an Office 365 operated by 21Vianet Public Website, to make sure people can get to it without having to type “www”, you need to set up redirection. After you follow these steps, both http://fourthcoffee.com and http://www.fourthcoffee.com, for example, will take people to your website on your fourthcoffee.com domain.
There’s one exception: If you chose to have Office 365 manage your DNS records in the Microsoft 365 domains setup wizard, you don’t need to take the extra steps here. When Microsoft 365 manages your DNS records, it automatically sets up DNS records that send people to your domain’s Microsoft 365 website, with or without typing “www” in the URL for your site.
If instead, you manage your own DNS, you’ll have to set it up yourself. Choose the link for your DNS host below to set up the redirection to make sure people get to your Microsoft 365 website without adding the “www”.

If your DNS hosting provider doesn’t offer URL redirection, buy it elsewhere
If your DNS host doesn’t offer redirection, you can use another company that provides URL redirection services. There are a number of companies that offer these services. To set up redirection, you buy an Internet link from the company, and the link redirects people to your website by mapping the domain without “www” to the fully qualified domain name for the site.
