Poll Email from Microsoft Exchange EWS API Plugin Issue

Question

Hello - 
 We are trying to use the Poll Email from Microsoft Exchange EWS API Plugin to retrieve emails from the office 365 mailbox . Our Mailbox is on cloud and we have to connect to the EWS service URL via a proxy . So we need to set the proxy flag as yes while called this plugin . The issue is when we setup the proxy flag as Yes . The plugin is asking for proxyUsername and proxyPassword . Our server proxies do not authenticate so we don't have these credentials . 
 We are trying to pass them as null on the third party credential screen but the plugin keep complaining with the error " Required field proxyUsername does not exist in SCS " . It looks like when we add these fields on the third party credential screen , the key value changes to lower case but the plugin is looking for parameter "proxyUsername" . 
 
 Has anyone else tried to pass the proxy details to this plugin ?

HI harveens0001 , 
 As per the plugin's code it does a case-sensitive search based on the keys "proxy U sername", "proxy P assword" if isConnectedViaProxy flag is set true. So unless the plugin is updated to refer the valid field names that is allowed in Appian Credential store, this plugin cannot handle proxy configuration.
