Once your Office 365 subscription has been setup, you will need to configure your DNS records for the services to begin working. Note that this only applies to your production domain, the temporary domain (example.onmicrosoft.com) already contains all the required entries.
You can retrieve the list of records specific to your domain through the Office 365 Admin panel, under Domains, by selecting either start setup, complete setup, or manage DNS.
A general list of the DNS entries required is show below:
