I use Thunderbird as my email client for google gmail accounts. My ISP is Verizon. For the past two weeks, I have not been able to send emails. I have deleted and reloaded Thunderbird and delete my old profiles. Nothing I have done so far has corrected the problem. I have tried all the recommendations on you help site. Attached are the TB error message, the Outgoing SMTP settings and the Windows 10 Secuity settings. I do not have a separate fire wall of antivirus program.
Any help would be appreciated. Gary Cogdell [edited email from public] @gmail
