O365 is a subscription service provided by Microsoft and includes elements of installable software (i.e., Word, Excel, etc.) mixed with cloud-hosted versions of its software solutions (Exchange, SharePoint, etc.). It is a way for Microsoft to bring together many of its enterprise offerings into a convenient wrapper that businesses can subscribe to. In O365, there are many different tiers of core subscription licenses that usually build on top of each other, and there are a plethora of add-on licenses to let a business pick and choose what additional features they want. Subscriptions come in three broad categories: Home, Business, and Enterprise.

You might see Office 365 and Microsoft 365 referenced together; it can get confusing, as Microsoft is rebranding some of the non-Enterprise plans from “Office” to “Microsoft.” The difference used to be that the “Office” or “O” plans contained Office software or Office services (Exchange, SharePoint, Skype for Business, Teams, etc.), and the “Microsoft” or “M” plans took the included offerings further, incorporating Windows 10 Enterprise licenses as well as the Enterprise Mobility + Security (EMS) tools. For our purposes, when looking at the Enterprise plans, consider O365 plans as a subset of M365.

Teams is provided only as a cloud service, meaning that there is no edition that you can install on your own servers. It is generally provided as part of O365 subscriptions because it relies heavily on the rest of the Microsoft cloud offerings for its core functionality. (That said, Microsoft has released a cut-down version of Teams for free, but that is not something to consider for this exam. See www.microsoft.com/en-us/microsoft-365/microsoft-teams/free for more information.)
