I'm trying to find a way to have the 'Open this task' button in Outlook when a task notification from a SharePoint 2013 Workflow is sent to a user.
We have been working on upgrading our SharePoint 2010 installation to 2013. Most of our sites are easily converted, but we have one business critical workflow that is keeping us from finishing the upgrade. This workflow is a simple approval process which assigns tasks to users in sequence. If all users approve, it sends an email into our ticketing service so we can apply the change requested. I am trying to duplicate this functionality using a 2013 workflow and the Task Process action.
However, whenever the task is sent out to the users, the 'Open this task' button in Outlook does not appear. I've done some digging, and I believe it is tied to the
Content-Class header of the task alert email. From SharePoint 2010, the header is
MSWorkflowTasks, where from 2013 it is
IPM.Note.Microsoft.Workflow.2013. No other headers are significantly different between the two emails.
Is there a way I can change the headers of those emails sent from 2013 to
MSWorkflowTasks, or am I going about this the wrong way? Having this button is fairly important in our process, as it does allow us to (at least slightly) obfuscate the workflow process from the users, and the users have grown dependant on it.
