Microsoft 365 (the new package of offerings formerly known as Office 365) is Microsoft’s cloud service offering for individual productivity, team collaboration, and enterprise communication, complemented by a set of security and compliance capabilities.
Microsoft offers several services bundles for Microsoft 365, and it recently rebranded the personal and business market focused versions of Microsoft 365 under its wider Microsoft 365 nomenclature. For the time being, the Microsoft 365 plans focused on the enterprise market are still available with Microsoft 365 branding. It is unclear how long Microsoft will retain the Microsoft 365 E3 and E5 service names, but its challenge will be differentiating these from the duplicated stream names in the current Microsoft 365 plan family (which could be as simple as jumping to E3, E5, E7 and E9, but conjecture on branding directions for Microsoft is not our intent). This white paper focuses on the Microsoft 365 plans targeted at the Enterprise market E3 and E5.
