A client Server was not configured. At the moment the Exchange Server receives Emails but the clients cannot connect to the server. Certificates in ISS is not configured correctly at the moment and OWA Virtual Directories are disappeared. ECP and Powershell are not available due to the certificate issue. I am looking for help
1) Fix the ISS - Exchange Certificate issue
2) Install the OWA virtual directory
3) Check that Clients can connect with OWA
The exchange Server is hosted on a Windows Server 2012 R2 in SPANISH!
