Exchange Connector failing with error "Failed to start ExchangeConnectorListener"?
Table of Contents
When we run exchange_server_url/VtigerExchangeConnectorListener/Service.asmx it should give us a response of "Push Notification" service. If it gives an error saying "Failed to load ExchangeConnectorListener", the the problem might be with .net framework. 1) Exchange 2010 should have 3.5 .net installed2) Exchange 2013 should have 4.6 .net installedThese .net versions are inbuilt features for Exchange server based on version. If we don't see those .net framework in the Control Panel then we should install it manually or using Command in Power shell and reinstall the plugin.
