Set-ClientAccessServer –Identity SERVER_NAME -AutoDiscoverServiceInternalUri: https://example.com/Autodiscover/Autodiscover.xml

Set-UMVirtualDirectory –Identity: “SERVER_NAME\UnifiedMessaging (Default Web Site)” –InternalURL: https://example.com/UnifiedMessaging/Service.asmx

Set-UMVirtualDirectory –Identity: “SERVER_NAME\UnifiedMessaging (Default Web Site)” –ExternalURL: https://example.com/UnifiedMessaging/Service.asmx

Set-ActiveSyncVirtualDirectory –Identity: “SERVER_NAME\Microsoft-Server-ActiveSync (Default Web Site)” -InternalURL: https://example.com/Microsoft-Server-ActiveSync

Set-ActiveSyncVirtualDirectory –Identity: “SERVER_NAME\Microsoft-Server-ActiveSync (Default Web Site)” -ExternalURL: https://example.com/Microsoft-Server-ActiveSync

Set-WebServicesVirtualDirectory –Identity “SERVER_NAME\EWS (Default Web Site)” –InternalUrl: https://example.com/EWS/Exchange.asmx
