I am a system engineer with 15+ years of experience of Microsoft server products, especially Active Directory, Exchange Server and slightly less Hyper-V and MS SQL Server administration. Now I'm working mainly with Windows Server 2012 R2 and Exchange Server 2013, in part with Windows Server 2016 and have a lab with Windows Server 2019
I think I can help you
