Has anyone gotten the Excel Connector (https://code.google.com/p/excel-connector/) to work in Excel 2016? 

The app canvas in Salesforce is refusing to load Oracle CPQ Cloud at all for external users (partner communities) due to "insufficient privileges". This happens when attempting to create a new eSales Quote as well as when you try to open an existing Quote. We have setup the debug log for a partner community user in Salesforce, we have three documented events logged when we reproduce the error. This error started happening after the upgrade to Summer '15, looking for an explanation as to why partner community license profile produces insufficient privileges error. 

We have already covered basic premises of profiles, and each bigmachines permissions are fairly consistent across all profiles. Would like extended details on the insufficient privileges error. Already looked at general causes for insufficient privileges:
