I have installed Exchange 2016 and for some reason when I am accessing the Exchange Management Center I can see the login page but after a successful login, he navigates me to: http://localhost/owa with a white page showing HTTP error 503.
Also when trying to access Exchange Management Shell, the shell throws me an error: "WinRM cannot process the request because the input XML contains a syntax error"
I tried to change the certificate in the binding on 443 and 444 to the "Exchange Server" certificate - didn't work.
But for some reason I have too many certs: Link to the Certs in Certificates MMC
this is how it looks like in the IIS window: Certs in IIS
Maybe I need to emove all of them and create a new Certificate? Note: I DOn't want a "GoDaddy" like cert, because it's only for local purposes
