SYMPTOMS

In this scenario, your program receives the following error code from the Exchange Server computer:
CAUSE
This problem may occur after you install the hotfix that is described in the following Microsoft Knowledge Base article:
843523 Memory leak occurs when you run a program that uses the incremental change synchronization API on your Exchange Server 2003 computer
This problem occurs because of a memory leak that occurs in the ICS object in Emsmdb32.dll. In this scenario, when you run ICS, every one of the ICS download synchronization operations uses memory. However, these operations do not release that memory. Therefore, when you run ICS in a loop, the program eventually runs out of memory.
