Can you please have a short look on that attached picture:
it is strange looking case when Active Directory shows two objects for the same one created person, with a long CNF:.. kind of text in the Name.
Assumingly the system generated that automatically, have you seen maybe such one? What can be the root cause of that?
Checking the email address in Exchange 2010 that is also strangly showing two lines for one email address, but that so should be definitely unique in Exchange
