Michael Reinders Contributor

Michael has been an 'IT Pro' since 1998. He has worked predominantly in the Windows world including client and server operating systems, on-prem systems engineering (AD, DNS, etc.), and over the last ten years or so has embraced and immersed himself in all things Microsoft 365 - including Exchange Online, SharePoint Online, Teams, OneDrive, and Azure Active Directory (AAD). He has written articles here on Petri based on these technologies and also published a larger series about 'Upgrading to Windows Server 2022' this past summer. Michael strives to help other IT Pros with getting more efficient (especially with PowerShell) in their day-to-day tasks and offering solid assistance on larger projects.
