Who this book is for
While Office 365 can make administration of enterprise-grade mail platforms simpler, readers of this book will still require an understanding of how e-mail systems work and familiarity with DNS and various mail platforms.
It is expected that readers will have at least basic IT skills in order to perform a migration to small business plans. Readers who will be using the enterprise plans and looking at hybrid environments with Exchange Online will need a far greater level of familiarity with Active Directory and Exchange Server.
Ultimately, this book can be categorized as being useful for small business owners with some level of technical understanding, through to corporate messaging administrators and IT consultants.
