![]() ![]() In some cases, a CNAME record is too blunt to accommodate the various certificates and naming in use in your environment – most often your Hybrid environment. Typically, Autodiscover uses a CNAME record called, unsurprisingly: “autodiscover”, to find the Exchange services configured with your domain name. So in no particular order, here are some common services you’ll be working through: AUTODISCOVER Once authorized, you can start to enable services against your domain but the order you do them in will depend on how you’re going to migrate or enable services. Microsoft will ask you to create a custom TXT or MX record to demonstrate that you have control of the DNS for the domain name and you’re authorized to use it. The first entry you’ll be asked to make in DNS is to show that you own the domain. The simplest solution here is to let Microsoft manage it for you but where’s the fun in that!?Īssuming you’ve registered your domain name and you’re managing the DNS yourself, there are different types of DNS records you’re going to come across. Once you have your tenant, one of the first things you’re likely to want to do is configure your very own domain name.

When you first sign up to create an account in Microsoft 365, you will be asked to choose a name for your new tenant. ![]() So, what does it do in Microsoft 365?

During the setup of services for Microsoft 365, Microsoft asked us to configure several DNS records for our domains, so I thought it might be useful to provide a little background information about what they’re for, plus some tricks and tips.įor most people DNS (the Domain Name Service) is a hidden background service but, without exaggeration, it’s invention in 1983 into the then mysterious word of inter-networking, was one of the most important steps in creating a scalable, global network as it allowed people to refer to relatively abstract IP addresses using a recognisable and orderly naming system. ![]()
