I have list of employees stored in a sharepoint list with first name, last name and email address. I have created a site workflow to send emails to all the trainees in there. However I am new to forms so not sure what is the best way for them to complete the training task. I have tried assign to do task and send an email to all with the same link but this will not complete the task assigned to them and they will keep getting reminders.
The users are outside the on premise SharePoint deployment so I am using the forms live solution to get users which are outside the domains. Attached is the workflow and nintex form screenshots.
