Error 503 service unavailable Exchange dashboard

Copper Contributor

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.
