Cause

Reviewed Sharepoint quarantine configuration on the Enforce. 
Looked at jcifs.properties, the jcifs.smb.lmCompatibility setting was set to 1 and should be set to 3

Environment

DLP 14.6 MP1
SharePoint 2013

Resolution

Set the jcifs.smb.lmCompatibility setting to 3 
Quarantine should now work as expected
