title: How to get notification of workflow errors?
body: <p>I am having issues were a workflow is stalled because there is an issue with sending an email (send email activity). Typically, this is simply solved by resuming the workflow. I'm wondering if there any way to react to a workflow error, so the user knows they need to go in and resume the workflow.</p>
  
  <p>I'm also wondering about this relative to a workflow that is attempting to assign a task to a user who no longer exists in the CRM or one that has an invalid email address, which I'm assuming would cause errors in workflows as well.</p>
  
  <p>Any other suggestions related to this sort if issue would be welcome.</p>
  
  <p>Thanks!</p>
