The RapidStart Field Service App provides automated emails. An email will go out to your Service Contact (Customer) when a Dispatcher creates a Service Appointment and also when your Technicians update their status regarding Service Appointments on the Mobile App. You can deactivate the Work Flow if you want to disable this functionality. The following steps will require the user to have the System Administrator or System Customizer roles.
Start by going to https://make.powerapps.com/
Click the Gear (1), then “Advanced Settings” (2)
Clik the arrow next to “Settings” (1) and then click “Processes” (2)
Locate the workflow process named “Service Appointment – Send Status Alerts” and tick the box (1), then click Deactivate (2)
Note: Editing the email templates is done from the Dispatchers app.
