Sort of a stupid question I have a friend that I haven't seen in years but we've corresponded through email for the past six years as our only means of communicating. We usually write about once a week or so but never go longer than a month. The last email I got was in the beginning of July and now every time I send an email it comes up as undeliverable mail. Now I can't figure out whether or not something happened to him or he closed his account. There was no discord or anything that would lead me to believe that he blocked me or something. I'm getting kind of worried. Is there anyway to see if an account was closed or something. He uses hotmail.
