title: sharepoint 2013 task not showing open this task button
body: <p>I've been trying to find answers to this situation in other threads/sites, with no success.</p>
  
  <p>Just starting with SharePoint 2013 and using SPD, I created a very basic list with a text field and a date. If I create and assign a SharePoint 2010 workflow, and have the following as a workflow step:</p>
  
  <pre><code>Log STARTED to the workflow history list
  then Start Approval process on Current Item with &lt;my email&gt;
  then Log FINISHED to the workflow history list
  </code></pre>
  
  <p>An email is sent to me with a button Open this Task in Outlook's ribbon - this is what I want, so far so good... FYI, all options to start approval process are default, and workflow is expected to pause until task is approved/rejected.</p>
  
  <p>If I delete the 2010 workflow and create/assign a 2013 workflow with these steps:</p>
  
  <pre><code>Log START to the workflow history list
  then Assign a task to &lt;my email&gt; (Task outcome to Variable:Outcome| Task ID to Variable:TaskID)
  
  if Variable:Outcome equals Approved
     Log APPROVED to the workflow history list
  Else
     Log REJECTED to the workflow history list
  
  Go to End of Workflow
  </code></pre>
  
  <p>I receive an email without a Open this task button, and users need to open the task that was created, edit it and then click on [Approve]. Too many additional steps.</p>
  
  <p>Both workflows (2010/2013) are set to start automatically on any changes.</p>
  
  <p>Apologies, can't copy/paste screenshots here, since I'm posting from my personal laptop. Any help is really appreciated here.</p>
  
  <p>Thanks!</p>
