DescriptionQuota - configuration errors (recoverable)
Event InformationAccording to Microsoft :
CAUSE:

This alert is generated when the quota usage for one or more directories seems to be incorrect. As a result, quotas might not be properly enforced.
Possible causes include:
1.The quota minifilter driver was attached to a volume that was not cleanly dismounted (system failure).
2.The quota minifilter driver was attached to a volume after it was manually detached, which allows data to be saved to the volume without updating the quota usage information.
3.Transient errors occurred while processing I/O operations, which may have resulted in incorrect quota usage.

RESOLUTION:
The system should be able to recover automatically form this state. You should monitor for an extended period of time whether the alert is resolved. If it is resolved, initiate a manual rescan of a volume using the File Server Resource Management (FSRM) command-line tools.
