+*                At all times:
+*                - mtm installation/removal
+*                - Message Server events:
+*                    * EMsvEntryCreated
+*                    * EMsvEntryDeleted
+*                    * EMsvCorruptedIndexRebuilt
+*                    * EMsvMediaChanged
+*                - Ecom service event arrives and SendUI Ecom service count has 
+*                  changed since last boot.
