How do I sing up to Microsoft for support

[Julia]

Every time I have tried to sing up, I received an error message.
"The portion of your email address that follows the @ symbol is part of a
reserved domain. What does this mean? what should I do?

 

[JoAnn Paules]

I don't know where you're trying to enter this information. What support are
you trying to sing? (I really like the idea of someone singing their tech
support stuff.)

Look carefully at the "e-mail" address that you are putting in. And then
use the correct domain for the section after the "@" symbol.
