Can't send SMTP mail after setting Default Security in Office 365
After I activated the 'Default Security' in Office 365, the multifunctionals can't scan-to-mail . I get error SmtpCmdResp: 535 5.7.3 Authentication unsuccessful [LO2P265CA0457.GBRP265.PROD.OUTLOOK.COM] --readSmtpResponse SMTP authentication failed after sending password. Check your username/password or your SMTP server's auth settings Settings: smtp_host: smtp.office365.com smtp_port: 587 Before activating Default Security there was no problem.Solved62KViews1like19CommentsRe: Can't send SMTP mail after setting Default Security in Office 365
LusoAdmin What I found out for new tenants: Disable the default security settings Enable the MFA on all users, one by one Wait some minutes Disable MFA for all users, one by one And: tadaaa , SMTP works again .55KViews0likes1CommentRe: Can't send SMTP mail after setting Default Security in Office 365
Today I had the problem again with a new Office 365 tenant. He couldn't send smtp mails. It looks like MS is activating the Default Security for new tenant now. Lukely, after disabling the Default Security smtp sending was working.56KViews0likes8CommentsRe: Can't send SMTP mail after setting Default Security in Office 365
Forrest_H I use Kyocera devices. SMTP used to work, until I activated Default Security. For new Office 365 tenants, Default Security is now standard set to 'on' , so new Office 365 users won't be able to send SMTP mails with multifunctional devices. I was hoping there would be a simple way just for one user (or shared mailbox) to send SMTP mail.60KViews0likes1CommentRe: Can't send SMTP mail after setting Default Security in Office 365
VasilMichev Nah, i'm more the 'let's see what this button does' type of guy 🙂 MS is expert in producing large quantity's of text with very little info. Especially if English is not your native language it's sometimes very difficult to follow. Do you think there is a way to **bleep** a little hole in the default security , just to allow one mailaccount to send mail via SMTP ?60KViews0likes1Comment
