How to Add a New Domain to Office 365
Adding a new Domain in Office 365 is a pretty straight forward process, in this post I will do a quick walk through of how to add a new Domain to an existing tenant.
To get started you need to be logged in to the Tenant with a Global Admin account and then Navigate to Setup and then select Domains.
From the top menu on the Domains page select + Add Domain
On the next page, you will be prompted to Enter the new Domain Name which you want to add to Office 365.
Click on Next after entering the domain name.
On the Next page, you will need to verify that you own the domain.
For the purpose of this post I will select “Sign in to GoDaddy (recommended)” as this is where my new domain is hosted.
After selecting your verification option click on Next.
The GoDaddy login screen for verification will Pop up, enter your User Name and Password and click Login.
On the next page click on Accept this will allow Office 365 to make changes to your domain.
Once the verification process is complete, you will be redirected to the next page which is selecting the option of updating your DNS settings.
I will select the (Add the DNS records for me (recommended)) option. This way new DNS records will automatically be added when new features are being released which requires additional DNS entries.
Click on Next to move on.
After clicking on next, Office 365 will go ahead and add the needed DNS records to your Domain, and after that you will receive the following output of all the records added to your domain.
To complete the process, click on Next.
You will be presented with the following page, stating your Domain is all setup.
After clicking on finish, your newly added domain will be listed under your validated domains.
And that is how you can quick and easily add a new Domain to Office 365.
