To be able to send mails over Simple MAPI/XMAPI from a 32-bit application via a 64-bit application (e.g. Microsoft Outlook 64-bit), use the mail proxy in the form of the two files cmMP32.exe/cxMP32.exe. These require registration via /regserver with administrator rights. Register both EXEs to be able to address 32-bit applications as well. For further information, please refer to the "Redist.txt" file in the "Documentation" subfolder of your List & Label installation.
