I have SQL Server with Database mail sending emails by Office 365 administered by client.
SQL is configured to use SSL, smtp.office365.com and port 587, account name and correct password.
It was working perfect, but few days ago sending stopped. I investigate that now smtp.office365.com needs STARTTLS command do relay mails.
What have to be done on Office365 connecor or what you suggest to chage on SQL Server database mail to allow use Office365?
