Dynamics CRM 2015 SharePoint 2013 Integration Problem

Hello,

I'm using CRM 2015 on premise with Sharepoint 2013 on premise, I've already configured the integration via list component, but one I click on documents on account or contact form, CRM always asks me to approve the creation of folder in Sharepoint, I always click on OK but that popup stays and asks me again and the folder is not created.

Could you please help.

Thanks.
