Event InformationAccording to Microsoft:
This problem can occur if the message has more than 32,766 (0x7FFE in hexadecimal numbers) recipients defined. The Internet Mail Service uses Messaging Application Programming Interface (MAPI) to create non-delivery report (NDR) messages, and attempts to add the recipients to an NDR message that MAPI is creating. MAPI uses the Emsmdb32.dll file to communicate with the information store, and the Emsmdb32.dll file has a limit of 32,766 recipients defined for the number of recipients on a single message.
