A protocol violation error is returned in MAgE logs when connecting to an Exchange 2013 platform
A protocol violation error is returned in MAgE logs when connecting to an Exchange 2013 platform. All traditional pre-requisites like name resolution and permissions may be ruled out, but an error similar to the following may be displayed in the MAgE logs:
2015-02-1116:29:28.1415Px1568Tx2CA18C4M133ErrorMicrosoft.Exchange.WebServices.Data.ServiceRequestException: The request failed. The server committed a protocol violation. Section=ResponseStatusLine | at Microsoft.Exchange.WebServices.Data.ServiceRequestBase.GetEwsHttpWebResponse(IEwsHttpWebRequest request)
In this particular scenario, an F5 load balancer was not configured correctly, and did not allow traffic persistently.
Consult F5 resources to ensure protocol violations are not being caused by load balancer configuration.
