Go Here: iCloud unknown error 0x80004002 - Microsoft Community. That is a 3-day old post, as of this reply.
According to the third- and fifth replies-down, it is an addin for Windows, that apparently is missing for use with iCloud, respectively. Someone unwise on the forum said that they got it from a Third-Party. But, only get it from Microsoft, and no where else. Getting it from a Third-Party could make it a scam.
