Join David Elfassy for an in-depth discussion in this video Add a domain in Office 365, part of Office 365: Deployment.
- [Instructor] Likely the most important element that identifies your location throughout the entire internet is the domain name portion of your email address, or what we reference to as the SMTP suffix, anything that comes after the @ sign. So if your email address starts with your first name, and then an @ sign, whatever comes after that is your SMTP suffix, or your domain name. In Office 365, we must set up a domain, at least one domain, in order to be able to receive emails and to be able to authenticate and access Office 365.
You see that I have several domains that exist in my tenant, in my Office 365 subscription, and I can add more by clicking on the add domain button. I'll do that in a few minutes. First, I want to take a look at the existing domains. So I'm going to click here on the elfassy.ca domain, and you'll notice that as soon as you click on the domain, you're presented with lots of information that is your recommended DNS settings. So this is not information that is currently configured, this is information that you should configure in your DNS database in order for the rest of the world to find your users inside of your domain.
So these are all DNS records that you must add to your DNS database, and they all serve a different purpose. So we have here email records for email, such as the MX email record, so the MX, or the mail exchanger record is the record that identifies your email servers in the global internet. And so if you're going to be hosted in Office 365, your email servers are going to be on the outlook.com domain in Office 365. Text records are used for anti-spam purposes, and an auto discover record that we discussed earlier in this course is used to allow your Outlook users to automatically discover, or automagically discover, their infrastructure in Office 365, by simply putting in their email address and a password.
They don't need to actually know the name of the Office 365 server when they configure Outlook. There are other types of records, and again, these serve different purposes, some of these are used for Skype for Business to have these online meetings, Mobile Device Management if you're using Windows Intune, or you have here an additional Office 365 record, this is used for client deployment. So there are several records that serve different purposes. Do I have all these records configured? Now I don't know if I have all of these DNS records included in my database.
All I do know is that Microsoft is recommending that I create these records to be able to use the Office 365 client applications. If I want to validate that these records are existing, I'm going to click here on Check DNS. So Check DNS is actually doing a query on the public DNS servers, and it's going to validate whether or not these records are all there. I can tell you right away that not all the records are there because I did not create the records for Windows Intune or for client deployment.
So those records are not there, and that's why I have some specific DNS record errors. So let's go down and take a look. First of all, the MX record, I've got my expected record that is there and it validated that, validated all the details of the records. And when I go down into the CNAME type records, you'll notice that I have my various autodiscover and Skype for Business records, but I do not have the enterprise registration records that are used for enterprise management, or desktop management. If I go down the list, I've got my text records for anti-spam and SRV records as well that are used for anti-spam and for Skype for Business.
So these are the various records that are available in my DNS database, and actually it's gone on and done that verification for me through the Office 365 admin center. Now I have an option here to fix my records, and the reason why I have this option is because I've integrated elfassy.ca, my domain, into GoDaddy, so I've purchased it from GoDaddy, and my DNS is also hosted on GoDaddy. Now there is a synergy, or a collaboration, between the two companies when it comes to Office 365, and I can allow it to automatically update my records by putting in my authentication to GoDaddy within Office 365 to GoDady DNS servers, and therefore it will have all of the DNS records that it's asking for.
So that's how I can validate my DNS records. I no longer need to use a command line tools. There are, of course, command line tools such as NS lookup that you can use to do this, but it has now been integrated as part of the Office 365 admin center. Now I mentioned before I can add a domain, or I can buy a domain. If I click on buy a domain, I will be linked to GoDaddy, and I will go directly to the GoDaddy website to buy a domain, and again, that domain will have that synergy with Office 365.
If I own a domain that I've bought from another provider, or a domain that I've recently bought from GoDaddy even, and that I would like to add it here, I can click on Add Domain, and there I'm prompted into the wizard, where I will add the name of my domain. It will verify that the domain is really owned by me, and there's a DNS verification for that, and then it will provide me with all the DNS records that I need to add to my domain in order for it to show up over here in my interface. Once I have added a domain, it will be available as one of my domains that is part of my tenant as long as the DNS information proves that I really own that domain.
This course details the process of moving your network to Office 365 by deploying a new Office 365 subscription. David Elfassy covers creating user accounts, adding domains, and configuring email, directories, conferencing, file sharing, and valuable business services such as PowerShell and SharePoint.
