hi I can't send or receive message ikeep getting windows live mail error id 0x800ccc90 can anyone help

Could be many things.. but I'm going to take a stab at this being a corrupt email.

What email account is this getting the error? (Like, Yahoo? Gmail? Etc)

Go to the webmail version of that account - delete any spam - better yet, check all the emails... try not to keep any (unless its important - delete it)

Then try again.
