Have you searched online? Type Microsoft error code and the code you have, and it will come up with descriptions, although many codes are generic. If MS come up in your search, go there first. If I get a min I'll have a browse. If you have no joy you'll have to contact MS. This happened on my XBOX one, couldn't sign in etc. Rang support and another email address had been linked to the device, and NOT by me!! So there is an other avenue to explore.
Best of luck!
