Adding Another Domain Name in Microsoft 365

Adding Another Domain Name in Microsoft 365

Managing multiple domain names for your business can improve your customer reach and help avoid missed communications. Whether your business uses different domains like contoso.com and contoso.net for various purposes or needs to add a domain for better spelling recognition, Microsoft 365 makes this process seamless.

In this article, we’ll guide you through the steps to add another domain name to your Microsoft 365 setup. This example will include registering a new domain and configuring it for email purposes.

Why Add Another Domain?

Your business might benefit from adding an additional domain for several reasons:

1. Alternative Spellings: Customers often mistype company names. For instance, if your business uses contoso.com and people frequently type contosso.com, registering the alternative ensures you don’t lose valuable connections.
2. Different Purposes: You may want to use one domain for your main website and another for specific projects, campaigns, or services.
3. Brand Protection: Registering similar domain names protects your brand identity from being misused by competitors or malicious actors.

Step 4: Configure DNS Settings

Microsoft offers two methods to configure DNS settings for your domain: manual or automated. For simplicity, we’ll focus on the automated method:

1. Add DNS Records Automatically:
   • Choose Add the DNS records for me, and click Next.
2. Select Services:
   • For this domain, select the services you want to enable. In this case, we’ll use it exclusively for email:
     • Enable Exchange: Ensure the domain supports email services.
     • Deselect Skype and Mobile: These services will continue using your existing domain.
3. Finalize Setup:
   • Click Next, then Finish to complete the process.

Step 5: Add Email Aliases for Users

To enable users to receive emails with the new domain, you must create email aliases. Here’s how:

1. Access User Management:
   • In the Admin Center, navigate to Users > Active users.
2. Choose a User:
   • Select the user for whom you want to create the alias.
3. Manage Email Aliases:
   • Click Manage email aliases, then select Add an alias.
4. Enter Alias Details:
   • Enter the username for the alias (e.g., support).
   • Use the dropdown menu to select the new domain (e.g., @contosso.com).
5. Save Changes:
   • Click Save changes, then close the window.

Step 6: Repeat for Other Users

If multiple users need access to the new domain, repeat the above steps for each of them. This ensures emails sent to their aliases will redirect to their primary email accounts.
