You set up email accounts in Tools - Accounts (can have multiple) and then
your mail comes to this Windows Mail program for you to read it all in one
place rather than having to access multiple web accounts. Do you have a
specific issue or error message you need help with (copy / paste please)?
Looks like you figured out Newsgroups . . . . . but you should change your
email address in that Newsgroup account to a phony one - otherwise the
spammers will get you !!
