Dynamics 365 has been configured to use server-side synchronization to process email. If you want to use the Email Router to process email, go to System Settings and change the Process Email Using field to Dynamics 365 Email Router. Custom Workflow Issue

Hello,

I am trying to send an email from a custom workflow. All my attributes are correct and on debugging, it fails at send email. It gives the error SQL Error Timeout.  The error it gives in Event Viewer is "Dynamics 365 has been configured to use server-side synchronization to process email. If you want to use the Email Router to process email, go to System Settings and change the Process Email Using field to Dynamics 365 Email Router". I don't know where to go from here. Please look the screenshot below. Please help!
