  • Microsoft SharePoint: Quota is only supported when setting the Path in the bookmark configuration to a Drives folder in a SharePoint site folder.

Some protocols do not report the available quota. Finder and Windows Explorer will show exabyte values in Online connect mode and the available space within the synchronization cache location on your local disk in Smart Synchronization connect mode for the affected protocols.

Note

Quota support can be disabled for all protocols.
