SYMPTOMS
When you (the administrator) are using the Exchange 2000 version of the Mailbox Merge program (Exmerge) to export mailboxes to personal folder files (.pst), the initial mailbox may not export and the following error may be logged in the Exmerge.log file:

CAUSE
This issue occurs because the full-featured Mapi32.dll file is renamed to Msmapi32.dll and moved to the Program Files\Common Files\System\Mapi\ \ folder when Microsoft Outlook is installed. A new stub Mapi32.dll file is added to the System32 folder to point applications to the correct Messaging Application Programming Interface (MAPI) configuration. However, the Exchange 2000 Mailbox Merge program needs direct access to the full-featured version of the Mapi32.dll file.



RESOLUTION
To resolve this issue, copy the full-featured Mapi32.dll file from the System32 folder of an Exchange Server computer (or any computer on which Microsoft Outlook 98 is installed) to the folder that contains the Exmerge.exe file. After you copy the full-featured Mapi32.dll file to the folder that contains the Exmerge.exe file, the Mailbox Merge program uses the full-featured Mapi32.dll file in the local folder and runs successfully.
