Hi Rohit,  thanks for this article, please could you expand on this so I may understand the wider picture.

• Where does the Client ID/Client Secret come from ? reading about this seems that it needs to be setup by the Admin who you are trying to connect too.  In my case I need my old SOAP function to connect to Exchange Web Services.  From reading article KB0816072 it seems the MS Azure Administrator have to setup this for you and supply?

 

• Also where do you apply the script,  currently we have Soap Function/message using Basic Authentication but MS have stopped this protocol.  Would we have to write a new Scripted Soap Service, as given in your example ?
