In May 2015, we announced the List Component deprecation as a result of SharePoint’s deprecation of the sandbox solution, a dependency of the List Component. Recently, SharePoint has announced the removal of code-based sandbox solutions in SharePoint Online.
Customers using the List Component with SharePoint Online are advised to migrate to the server-based integration immediately to avoid disruption of service. Sandbox execution for the List Component is scheduled to turn off on November 30, 2016.
Here are details from SharePoint’s blog post [See Full Post]:
See Set up SharePoint integration with Microsoft Dynamics CRM for more information on enabling server-based SharePoint integration.
Customers using the List Component with SharePoint on-premises deployments are not currently affected.
