OneDrive Sync supports syncing up to 1 million items on Windows devices, helping teams manage large document libraries and shared content at scale without compromising access across devices. This preview requires the Insiders ring and that devices meet minimum hardware and configuration requirements. Devices that don't meet these requirements continue to sync at the existing 300,000-item supported limit with no disruption.

Direct effects for Operations**
Increased Sync Limit
If the change to support syncing up to 1 million items is implemented without proper preparation, users may experience performance degradation on devices that do not meet the minimum hardware and configuration requirements, leading to slower access and potential data loss during sync operations.
