Hello everyone, please I need your help. My outlook account is neither sending nor receiving mails, each time I try, I get the response below: Your message did not reach some or all of the intended recipients. Subject: Test Sent: 02-Nov-20 16:04 The following recipient(s) cannot be reached: firstname.lastname@example.org on 02-Nov-20 16:04 None of your email accounts could send to this recipient. Please, how can I resolve this? Thanks.
