Capacity management - SharePoint Workspace limits

Limit	Maximum value	Limit type	Notes
SharePoint Workspace synchronization	30,000 items per list	Boundary	SharePoint Workspace will not synchronize lists that have more than 30,000 items. This restriction exists because the time to download a list that has more than 30,000 items is very long, and resource usage is high.
SharePoint Workspace synchronization	1800 documents limit in SharePoint Workspace	Boundary	Users are warned when they have more than 500 documents in SharePoint Workspace, but they can continue to add documents.
