We have a new employee taking over and I've been updating our forms so that she'll receive all the appropriate emails/ notifications/ tasks going forward. I've completed all this, but they still are not seen as a manager for certain people. The form process is that an employee will submit a request to their manager for approval before moving onto the next step. All other managers are working/ being registered as managers and can move forward in the forms workflow, but our new employee can't and the form gets suspended. When I go into Monitor to check what happened I cannot restart the workflow. The error message reads "Retry is not available for any steps in the selected instances."

How can I update the employee-manager relationship for our employees? We have a windows user director, is it found within here?
