Make sure this one is ticked when you go to more settings: My outgoing server SMTP requires authentication. As other mentioned already, double check on SSL and TLS. I believe it is SSL 993 and TLS 587 for Gmail account. Make sure there is no software like Stunnel, highly doubt someone will use such program at home but who knows. Malware could be culprit as well Is email going out with other client software like Thunderbird etc.? -----Original Message----- From: Blind-sysadmins [mailto:blind-sysadmins-bounces@lists.hodgsonfamily.org] On Behalf Of Barry Toner Sent: Saturday, September 19, 2015 12:59 PM To: 'Blind sysadmins list (blind-sysadmins@lists.hodgsonfamily.org)' <blind-sysadmins@lists.hodgsonfamily.org> Subject: [Blind-sysadmins] Outlook 2010 not sending mails Hi all, This has been puzzling me since yesterday. I visited a person's house to set up their emails in Outlook. I created 3 profiles to house each mail account, as this is the way they are used to it being set up on 2003. There are two BT accounts and one GMAIL account. All the accounts are using IMAP. No accounts are able to send mail, but can receive fine. I have checked Windows Firewall, and even turne dit off. I have removed AVG that another person installed in case for some odd reason this was blocking. I've verified that the BT settings match those found on, http://bt.custhelp.com/app/answers/detail/a_id/44917/~/what-are-the-settings -for-outgoing-and-incoming-bt-email-servers%3F I can confirm that the Outlook 2010 test in the email setup window completes by connecting to the outgoing server and sending a test mail. However, when we try and send an email to anyone the mails don't' go. I can confirm that another party outside of this scenario who shares the GMAIL mailbox can connect fine using Outlook 2010. I can also confirm that the BT IMAP accounts are sending and receiving mails and displaying the list of folders correctly on IOS. Is there something I could be missing? Any help greatly appreciated. Thanks, Barry. _______________________________________________ Blind-sysadmins mailing list Blind-sysadmins@lists.hodgsonfamily.org https://lists.hodgsonfamily.org/listinfo/blind-sysadmins ----- No virus found in this message.
