I assume this requires the MLO desktop client / PC running?
The best way in the future to set this up would be via the cloud.
Even better if it could be done with other triggers than due date. Such as a task/project getting a certain context or flag.
(Even better would be if the cloud could interact with IFTTT or Zapier but at least the triggered emails could help some of the way).
One way I would use it would be to give a project a "Project Support Information" marking and then trigger the creation of a folder for that on my Google Drive or Dropbox, with the same name as the project.
