At Microsoft Ignite 2025, Gaia Carini from the OneDrive product group in Redmond announced that a long-established threshold would be raised. She spoke of 500,000 files to be synchronized.

To get straight to the point: it won’t work with classic synchronization, but only with the Add a Shortcut to my Files function.

I first wrote about this in an article titled OneDrive for Business – Add Shortcut to my Files in the summer of 2020. The latest article dated March 10, 2025, on New naming convention for folder shortcuts shows that Microsoft is continuously working on this technology. I republished an article in English called Add to OneDrive on my website in October 2024 after the Tekkigurus domain was taken offline. This article has been read by more than 28,000 people.

Yes, it’s not easy. But it doesn’t fit into every SharePoint structure, having grown and changed in the file servers and not been adapted during migration to SharePoint.

As previously announced, the announcement to increase the previous soft limit for synchronization from 300,000 files to 500,000 files will first be rolled out in a private preview. This will then transition to a public preview before becoming available to everyone who uses

• Windows 11, Windows Server 2022+, or macOS from the last 3 versions has
• at least 16 GB of RAM, preferably 32 GB of RAM
• Uses an SSD as a hard drive
• and uses an Intel I5/Ryzen 5 processor or better
