Second updated edition of the unofficial manual for Google Workspace administrators, covering both Business and Education editions. This book is a practical, hands-on guide to configuring the Admin console according to recommended best practices and security standards. It includes step-by-step explanations, updated screenshots and hyperlinks to additional resources, also accessible in the print version via QR codes. Suitable for admins who are new to the console as well as those looking for a structured reference, it starts from basic operations and gradually moves towards more advanced configurations, including scripts and third-party tools. Compared to the first English edition, this updated version adds a full chapter on Generative AI (Gemini app, Gemini in Workspace and NotebookLM), a new Data chapter that brings together compliance, import/export and migration tools in one place, and revised sections on Drive, Directory, Meet, licences and Devices to reflect the latest changes in the Admin console. You will find guidance on the renewed Data migration hub from Microsoft environments, visual badges for files owned outside your domain, locked groups for sensitive scenarios, new Gmail-only and Archived user licences for managing former students and staff, updated ChromeOS and Google Meet hardware management, Workspace Studio for building internal agents and automations, and refined controls for Additional Google Services such as Google Play. From Provisioning to Apps, from Security to browser and device management, this guide offers ready-to-use advice for the most common Google Workspace settings, enriched with realistic scenarios and EDUCATION TIPS for schools. Whether you manage a small business domain or a large school or district, it is designed to be an interactive manual you can keep open next to the Admin console and rely on whenever you need to review or improve your configuration.
