I've released an updated version of my recurring workflow scheduler for Dynamics 365 Customer Engagement. This solution targets Dynamics 365 version 9, so it should work in all current Dynamics 365 online organizations. You can download version 1.3 of my solution from here: https://github.com/lucasalexander/AlexanderDevelopment.ProcessRunner/releases/tag/v1.3.
