When you export users to an .ldf file in Exchange 2000 Server, the Mailbox Reconnect tool (Mbconn.exe) silently exits when you click Save in the Save As dialog box

When you use the Mailbox Reconnect tool (Mbconn.exe) in Microsoft Exchange 2000 Server to export users to an .ldf file, the Mailbox Reconnect tool silently exits when you click Save in the Save As dialog box.

Note You can also use the Mailbox Reconnect tool to connect Exchange 2000 users to their orphaned mailboxes. This tool is especially helpful when you are replacing or adding an Exchange computer.

This issue is caused by a difference in the size of the OPENFILENAME structure. The size of the OPENFILENAME structure is embedded in the CFileDialog class between the Mfc42u.dll file from the Microsoft Windows Software Development Kit (SDK) that was released before January, 2000 and the Mfc42u.dll file from the Windows SDK that was released in January, 2000.
