Description

Microsoft 365 represents a combination of Office 365, Windows 10 and Enterprise Mobility offerings – providing the most complete set of SaaS technologies that Microsoft has to offer. With Microsoft 365, organizations can deploy a complete solution encompassing both devices and applications, along with applying security and compliance policies to protect the entire suite.

This course will help you as you plan your deployment of Microsoft 365, along with configuring and managing your tenant once it’s deployed. It also covers setting up and managing a Microsoft 365 subscription for an enterprise – including managing identities, security, compliance and the supporting technologies in the Microsoft 365 stack.

This course focuses mainly on setting up and managing a Microsoft 365 tenant – including the process for setting up a trial tenant, adding your own domains, and converting your tenant beyond the trial to a fully functional production environment. Now, these steps can seem to be very easy – just click a few options, answer a few questions, and you’re done. In fact, it is that easy! However, if you’re not aware of the big picture and asking some important questions along the way, you can end up painting yourself into a corner and causing problems down the road. At best, you might need to redo some things, at worst, you leave yourself with problems on your hands that might be difficult to sort out later.

After you’re set up, we’ll move on to talking about some of the things you need to consider in your day to day monitoring and management of your Microsoft 365 Tenant and the services that make it up. We’re also going to run through a few demos – showing you some of the practical steps involved, along with some tips and tricks we’ve picked up along the way.

Transcript

Microsoft automatically creates an onmicrosoft.com domain for you when you register for an M365 tenant. You're more than likely not going to want to use this name and will plan to use your own custom or vanity domain. But there's something to keep in mind when creating your tenant. 

When you register your tenant, the company name that you choose during the registration of your tenant will become your onmicrosoft.com domain. And this domain name cannot be changed later. I cannot stress this enough. Make sure you think through the name that you're choosing because you'll have that name for the life of your tenant. And the only way to change it at this point, is to migrate to a new Office 365 tenant. Not something that you'd undertake lightly. 

Now I know what you're thinking. It's probably not that bad, right? I'll be using my custom domain name anyway. You definitely will use a custom domain. And most of the times, your users won't notice the onmicrosoft.com domain. But there are still two place that your onmicrosoft.com domain will show up for your users to see. The first is on your SharePoint Domain Name. Your SharePoint Online Sites are named from the root of your tenant. So if you've named your tenant mydomain-test.onmicrosoft.com then your SharePoint sites will be mydomain-test.sharepoint.com. The second place is in your Skype for Business Meeting Invitations. Maybe not the biggest problem in the world, but it definitely doesn't look good, and is an easy problem to avoid by simply putting some thought into the domain name you choose when configuring your tenant.
