SYMPTOMS
If you move a mailbox programmatically by using the move mailbox method in Exchange 2000, an access violation may occur in the application that calls the move mailbox method.



CAUSE
This problem can occur because Cdoexm.dll loads Mapi32.dll explicitly from the Exchsrvr\Bin folder, to avoid conflict with the Mapi32.dll file that is included with Microsoft Outlook. However, if the application calls the MAPIInitialize function, Mapi32.dll is loaded from the Winnt\System32 folder. Because of this, two Mapi32.dll files are loaded in the application address space, which causes the access violation.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft Exchange 2000 Server service pack that contains this hotfix.
