MORE INFORMATION
For example, if you complete these steps, you may experience a memory leak in the Cdoexm.dll file:  Create a program, and then let the program repeatedly create and release an instance of the IStorageGroup interface. Start your program. Use the Performance utility to monitor the Process\Private Bytes performance counters of the program that you created in step 1. To do this, follow these steps:  Click Start, click Run, type perform in the Open box, and then click OK. Click Add. Click Process in the Performance Object list, click Private Bytes in the Select counters from the list list, and then click the process of the program in the Select instances from list box.</li> Click Add, and then click Close.</li></ol> </li></ol>

Note You may find that the Process\Private Bytes performance counters quickly increase even after the CoUninitialize function is called in the program that you created. However, significant memory is still leaked.
