After the renaming exercise in early 2020. Microsoft still offers the Office 365 license through the cloud. Office 365 remains the traditional cloud productivity suite that comprises of common Microsoft Office applications like Outlook, Word, Excel, and PowerPoint. A majority of these plans offer hosted Microsoft Exchange mailboxes along with various “add-ons” that add increased security and compliance for stand-alone office applications such as Project. The Office 365 suite is divided into two main categories as described here
Office 365 Business
Business plans include Essential, Business, and Business Premium. These plans offer a low-cost approach to provide key Office 365 services to clients with minimal needs. However, there are a few limitations to these plans which are important to note. For example, Office 365 Business does not include Shared Computer Activation (SCA) for Office products. This means that you cannot use Business plans with a Remote Desktop Environment (RDS) in Azure.
Office 365 Enterprise
Office 365 Enterprise plans include ProPlus, E1, E3, and E5. These plans offer key features that are geared towards Enterprise productivity which include options that are not available under Business plans. All these plans, except E1, include Office ProPlus with SCA and are suitable for use in an RDS environment. The Office 365 E3 plan is the most commonly used level within Enterprise plans as it includes Office ProPlus, Exchange, and important security and compliance features like e-discovery and archiving.
Office 365 also offers various versions of Enterprise plans for various verticals. These include Education, Government, and Non-Profit licensing. Each licensing model caters to specific requirements and has varying costs.
