The underlying cause is almost certainly that your plugin is running in the sandbox. The sandbox does not allow making authenticated calls to external web services (which I expect is how you're trying to connect to SharePoint).

If you have CRM OnPremise, then you can deploy the plugin outside the sandbox, whereas if you have CRM Online you'll need to move the processing into Azure (or elsewhere using a Web Hook) - see https://mscrmuk.blogspot.co.uk/2018/04/plugins-in-sandbox-and-why-you-dont-get.html for a bit more information
