XADM: Event ID 9202 Is Logged and the Exchange 2000 Mailbox Management Process Does Not Start Correctly

This article has been archived. It is offered "as is" and will no longer be updated.
When you start the Mailbox Management process in Exchange 2000, the following event is logged to the application event log:
Type: Error
Source: MSExchangeSA
Category: Mailbox Management
Event ID: 9202
Failed to open default message store.
This problem occurs if both of the following conditions are true:
  • You run a MAPI program, such as ARCServe 2000 Backup Agent, on the Exchange 2000 server.

  • The MAPI program impersonates a user account at runtime. The user account that the program impersonates is a different user account than the user account that starts the program. For example, the process runs under the context of the Local System account and is initialized under the context of the Administrator account.
In this situation, a problem exists with the Mapi32.dll component where the Exchange profiles for the user accounts are incorrectly deleted from the registry after the MAPIInitialize function is called. Even though the registry keys that store the Exchange profiles are the same, the shared memory sections that are used to determine if a profile is in use are different. However, in versions of Mapi32.dll that are earlier than 6.0.6448.0, the same shared memory is used. As a result, Exchange profiles are deleted from the following key in the registry, and the Mailbox Management process does not start correctly:
HKEY_USERS\.DEFAULT\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem
