Hi Kwaog,
Thank you for the explanation of what you have tried so far and what you are seeing (or rather, not seeing in the synchronisation).
There are two additional settings that come to mind which will have an impact on the synchronisation of the Accounts and Customers.
1. Search for and open the Microsoft Dynamics CRM Connection Setup page. In the ribbon, click on the Integration Table Mappings button. In the Integration Table Mappings page, locate the line with Name/Table value of CUSTOMER/Customer. Ensure that the far right column (Synch Only Coupled Records) is unmarked.
2. In CRM, for each Account that you wish to synchronise, the Relationship Type field value must be Customer. This field is not included in the Account page, by default. It must be added to the page.
If you can ensure that these (above) two settings are as suggested, then the Accounts from CRM should synchronise across to "Financials".
The Job Queues will drop to a status of On Hold when there are not records to be synchronised. In spite of the status, the records are still being monitored for changes/additions. When a change/addition is recognised, then the Job Queue will be automatically set back to an Active status and will run two iterations.
