Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
To get started, I need to know what type of computer you are using, a Windows XP, Vista, Windows 7, Windows 8, Windows 10 or a Mac.
If its a Mac, please check the OSX version as follows, Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
Also, how long ago did you set up the Microsoft account with the incorrect carter.net address? And is this issue stopping you from signing into your windows 8 or 10 computer? Or, if its some other issues please describe the problem as best as you can. Thank you,
Senior Technician and Network Switching Systems Operator / Maintainer.
