Damian Scoles has been an Exchange/Office Servers and Services MVP since 2013. Currently based out of the Chicago area, he started out by managing Exchange 5.5 and Windows NT. He has worked with Exchange Server since 1997 and has remained active in the Exchange community by contributing to TechNet forums, creating scripts for Exchange admins on the TechNet wiki, writing detailed Exchange blog articles, and running an Exchange/Office 365 user group in Chicago. As a second-time author, Damian has poured his knowledge of Exchange Online and PowerShell into this book. He hopes you will enjoy reading it as much as he did writing it.
