You can re-create OWA virtual directory:

Note: Do not forget to backup OWA settings first (e.g. internal/external URL)

Are you trying to log in from Exchange 2013 OWA into Exchange 2007 mailbox?
If yes, have you configured legacy OWA URL for Exchange 2007?

Can you connect to your exchange 2013 mailbox using e.g. Outlook or other non-OWA method?
Did you check event logs?

Hi Gurmeet,

1) Check if there is any issue with the XAML file type since its a fresh installation i suspect more on this file 
Find the file located in

C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\ecp\DDI\RemoteDomains.XAML
If you have any staging servers with the same version where it is working just copy this XML file or if you could find this file from the setup just replace with the existing one do an iis reset and see the results


2) Check on the Application Pools to view whether OWA and ECP Application Pool is running on .NET Framework v4.0. It maybe the incompletely or corrupted installation of Framework that causes this error.

3)Try to run the following command as Administrator:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

Change the MSExchangeECPAppPool from .NET Framework from v4.0 to v2.0. Then restart IIS and check the results.

4) Check the bindings of the default website to confirm to Microsoft recommended settings:

({http port 80 *}{http port 80 127.0.0.1}
{https port 443 *}{https port 443 127.0.0.1})
