Error 503 service unavailable Exchange dashboard
Good morning, I have installed Exchange 2019 (Cumulative Update 7) on a Windows Server 2019 Datacenter. All preliminary activities went right (installing .Net, installing Microsoft Unified Communication Managed API, preparing AD, ecc.). Of course WIndows Server 2019 hosting Exchange is domain joined. I have launched Exchange setup and procedure ended with no errors or warnings: all seemed fine. When I try to access Exchange Administration console (ECP) I got: error 503 service unavailable. What can I check? If need other details, please ask. Thank you in advance. Best regards. Marco
