we are running nintex workflow in office 365 (but we have mailboxes on premise only) - we only use Sharepoint online.
we would like the worflow to send tasks or at a minimum email notifications using the external email service. how can we set the workflow to send external emails (we only foudn the option email service with the option that says "External email service configured by Nintex" but no other details.
can you confirm how we can do that please? (sending either email notifications or tasks (ideally) to external users (who are not hosted on Office 365)
