For some reason everytime a user receives a task assigned by a workflow from SharePoint; and attempt to open the assigned task from within Outlook 2013 they get the following error :
An error occurred while retrieving the workflow details. This may be caused by:
1. Not having connectivity to the server.
2. The task no longer exists.
3. You do not have permission to access the task.
And I can basically rule out all possible errors. I have now searched and searched for solutions but can't seem to find any solution.
