I am after a simple workflow that will send an email when the 'Assigned to' field of a task item changes to anyone. The 'wait for field change' action only allows you to enter a value that the field should change to. Also I am using Office 365 Nintex Workflow so I cannot trigger a workflow on a conditional start..
I am not using the standard 'Send email when task assigned' option in SharePoint as I want to customise the email i.e. only display a few fields in the email. But if there is a way to customise the email in SharePoint that would solve this too..
