The fundamentals of administering Microsoft 365 and its AI: the core objects of Exchange, SharePoint and Teams, Zero Trust security with Microsoft Entra and Defender XDR, data protection and governance with Microsoft Purview and SharePoint oversharing controls, and the basic administration of Microsoft 365 Copilot and agents - licences, pay-as-you-go billing, usage, prompts and agent approval.
