You can re-create OWA virtual directory:

Note: Do not forget to backup OWA settings first (e.g. internal/external URL)
I Have two exchange 2013 fresh server but problem is same on both exchange server 2013
Exchange 2007 Sp3 to Exchange server 2013 CU8
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?

Exchange 2013 to Exchange 2007 OWA is working fine
New Exchange 2013 Mailbox is not open in Exchange server 2013 Server
Can you connect to your exchange 2013 mailbox using e.g. Outlook or other non-OWA method?
Did you check event logs?
Exchange 2007 Sp3
2 CAS Server-
1 MB Server
Exchange 2013 CU8
2 CAS+MB Server
I have created 2 New Mailboxes on Exchange 2013 Server and OWA is not opening on Exchange server 2013 Server.
Hi Gurmeet,
1) Check if there is any issue with the XAML file type since its a fresh installation i suspect more on this fileFind 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})
