Johnson had copied me on a mail he'd sent out to his team

Hi, geniuses!

I'm stuck with this sentence
"Johnson had copied me on a mail he'd sent out to his team" from the book Leaving MSFT to Change the World by John Wood.

I don't understand this sentence.
I'd really like to know what is meant by it and why it means that.
Please help!

1) Johnson sent out an email to his team

2) Johnson copied John Wood on that email (i.e. sent him a copy, too), even though John Wood was apparently not on Johnson's team.

Guest is right.

Also, should you wish to copy someone on an email, you can put their email address in the 'CC' or 'BCC' box (BCC I think means blind something, so that others can't see that you sent that person a copy).

CC is Carbon Copy i believe, so it's conceivable that BCC means Blind Carbon Copy.

<<so it's conceivable that BCC means Blind Carbon Copy. >>

Nowadays, bcc is usually just called "blind copy".

It's been decades since I've used carbon paper (cool stuff, though), along with mimeograph stencils and ditto machines. Never did get to use one of those Ozalid machines, though.

Thanks! I now understand what the meaning is.

Is that the most common expression when you want to mean something like that?
Is there any other way of saying that?
