This fix is a post-Office 2000 Service Pack 3 (SP-3) fix. To install the fix, you must have Office 2000 SP-3 installed. For additional information about Office 2000 SP-3, click the following article number to see the article in the Microsoft Knowledge Base:

Additionally, you may have to install Windows Installer 2.0 to install this fix. For additional information about the Windows Installer requirement for post-Office 2000 SP-3 fixes, click the following article number to see the article in the Microsoft Knowledge Base:

This fix also requires the addition of a new flag to be passed to GetHierarchyTable to disable the asynchronous hierarchy synchronization. The value of this flag is 0x4000 hexadecimal. Add this flag to the ulFlags parameter when calling GetHierarchyTable as:
hr = m_lpFolder->GetHierarchyTable( MAPI_DEFERRED_ERRORS | 0x4000, &m_lpFolderTable );
A call to Sleep can be made just before calling MAPIUninitialize if you suspect you are experiencing this symptom. The value that is passed to Sleep may have to be adjusted depending on your environment. Testing has shown that a value of 1000 or 2000 milliseconds is generally sufficient to make it possible for the IMAP store to close before uninitializing MAPI.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
