You may be confusing this with when the Outlook security model started throwing up an 'allow/deny' confirmation when an external programme attempts to create a message using Simple MAPI. A kludgy way around that is to install a utility called ClickYes which silently closes the Outlook dialog. A better way is to use something other than Simple MAPI. SMTP has nothing to do with Outlook, you're just connecting directly to a mail server (Exchange, whatever). Hosted Exchange on Office 365 does have limits on the rate at which you can submit emails and the number of submissions. This is to stop bulk emailing. If you want to do that, use Sendgrid or Mailjet etc.
Update: client is using Exchange server it looks like, and locally Outlook 2016. When I researched ClickYes above, it looks like that is for OLDER versions of Outlook.
