CU4 for SCCM 2012 SP2 and SCCM 2012 R2 SP1

1. MDM – Fixes the issue where the exchange connector synchronization fails. The errors are logged in a file EasDisc.log. Errors include “An item with the same key has already been added”. “Failed to check status of discovery thread of managed COM”. If you are seeing same errors in the EasDisc log file, then the CU4 should help.
