Exchange Hybrid Configuration Wizard
PROBLEM
When you run the Exchange Hybrid Configuration Wizard, the following error message is reported:
Updating hybrid configuration failed with error ‘Microsoft.Exchange.Management.Hybrid.CouldNotCreateOnPremisSessionException: Could not create On-Premisses Session: Could not open Remote Powershell Runspace: Connecting to remote server failed with the following error message: The WSMan client cannot process the requests. Proxy is not supported under HTTP transport. Change the transport to HTTPS and specify a valid proxy information and try again.’
CAUSE
There is a proxy defined in Windows which causes PowerShell to switch the communication protocol from HTTP to HTTPS which causes a communication problem.
SOLUTION
Remove the proxy configuraiton in Windows OS.
Use the following command to check if there is a proxy configured:
netsh winhttp show proxy
To remove the proxy configuration use:
netsh winhttp reset proxy
