Troubleshooting: Outlook Social Connector Provider error codes

Outlook Social Connector providers should return errors to the caller. Please note that Success, warning, and error values are returned by using a 32-bit number that is called a result handle, or HRESULT. An HRESULT is not a handle to anything; it is merely a 32-bit value that has several fields encoded in the value.

A positive result indicates success with status, a zero result indicates success without status (S_OK), and a negative result indicates failure. I have listed the couple of the error codes that I noticed…
