Is Dynamics hosted on the cloud or are you running it in house?  

We currently have Dynamics hosted in house and we can use Laserfiche Forms data and Laserfiche metadata to update Dynamics out of the box with the workflow update data activity.  We are moving Dynamics to the cloud and won't be able to use that anymore, but I know that Cities Digital has a Dynamics integration that will still allow for this functionality.  I imagine you can do the same thing with connector, but I could be wrong.
