SYMPTOMS
When you run a program that uses Collaboration Data Objects for Exchange Management (CDOEXM) on a Microsoft Exchange 2000 Server computer, the server may eventually stop responding to client requests.

When you use System Monitor to view the Private Bytes counter for the process that is associated with the program that uses CDOEXM, you may notice that the memory usage for the process continues to increase.



CAUSE
This problem occurs because of a memory leak in the Cdoexm.dll file.
