The Microsoft 365 Enterprise bundles basically are identical to their Secure Productive Enterprise E3 and E5 Windows 10 predecessors -- which consisted of Windows 10 Enterprise (E3 or E5), Office 365 (E3 or E5), and the Enterprise Mobility + Security suite (E3 or E5). Microsoft unveiled its Windows 10 Enterprise E3 and E5 and Secure Productive Enterprise subscription offerings at last year's partner show.
Microsoft's aim with Windows 10 Enterprise and Secure Productive Enterprise was to give more of its small and mid-size business users an easier way to move to more premium versions of its various subscription products.
Once Microsoft 365 Enterprise is generally available, Microsoft will discontinue offering the Secure Productive Enterprise bundle, officials said.
