You approved objects that fell into the non applied object category and now want to undo this action.
When approving non applied objects for matching this creates a pre-matching rule which is hidden. You can use the tool called "MatchingRulesViewer.exe" located at "C:\Program Files (x86)\Quest Software\Collaboration Services\3.7.0.058" to delete the pre-matching rule.
When you delete pre-matching rules for objects using this tool, if Collaboration Services was to perform a synchronization again which includes an object that there is a conflict for on the subscriber side, the conflict will appear in the non-applied objects container again in the Collaboration Services console.
