Adding your domain name to Office 365
The domains page shows all the domains your Office 365 tenant is associated with
and their respective status. As you can see, you can associate multiple domains to a
tenant. However, once a domain has been associated to an Office 365 tenant, you will
not be able to associate that same domain to another Office 365 tenant. By default,
you should at least see the domain name that you used to first sign up for Office 365.
It should be in the form of < Name >.onmicrosoft.com.
2. To associate a domain to this tenant, click the Add a domain link, as shown in Figure
Figure 3-3 Add a domain.
3. Click Specify a domain name and confirm ownership.
4. Enter your domain name in the text box and click next, as shown in Figure 3-4.
Remember that you can add only an Internet routable domain, and the domain you
specify must not have been previously associated with another Office 365 tenant.
Do not worry if you do not remember whether a domain has been associated with
another tenant. You will be notified if that is the case.
5. After you click next, Office 365 informs you if the domain has been previously
associated. If not, you can proceed to the next task, which is to verify the domain.
