Hi I'm getting the following error when sending an email using Windows Live Mail: An unknown error has occurred. Subject 'Re:' Server: 'smtp.myisp.net' Windows Live Mail Error ID: 0x800CCC0B Protocol: SMTP Port: 25 Secure(SSL): No No timeout, it happens pretty much immediately. I'm doing a "Reply All" to about 12 people. Same result sending from my other email accounts in Live Mail. Can receive email ok. Can send other email, including multiple contact emails. Just something about this email! Tried sending the email starting from scratch (not doing a "Reply All") but get same result. Searched Google without any success. Seems to be quite a common error ID. My ISP report no email issues on their side. We checked mail account properties and all was in order. They suggested turning off my anti-virus but this did not make any difference (shouldn't need to anyway!). They could assist no further. Nowhere left to turn. Would really appreciate some help. Thanks.
