Many clients, especially those with Enterprise Agreements, are being asked by Microsoft to convert their licensing agreements into Office 365 based subscription solutions and are confused by their options. This comparison is for clients who currently own just the Core CAL (client access license) and are considering moving to an Office 365 E1 plan with a Bridge CAL.
Let’s start with what is the same.
Both E1 and the Core CAL give you the right to run Exchange Standard CAL, Skype for Business Standard CAL (formerly known as Lync), and SharePoint Standard CAL on premise, in your own data center for your users. Both plans would require the requisite Server licenses purchases.
The Bridge CAL completes the traditional functionality of the Core CAL by licensing you for a Windows CAL, System Center Configuration Manager CML, and the Microsoft EndPoint Protection Antivirus service.
