SYMPTOMS
When you use MapiSend.exe from a command prompt to send an e-mail message, you may receive one of the following error messages:

Error: MAPI MapiSend Failed: 14

Error: MAPI MapiSend Failed: 21



CAUSE
This problem occurs due to ambiguous name resolution.

If the sender's mailbox alias is ambiguous, the following error occurs:

Error: MAPI MapiSend Failed: 14

If the recipient's mailbox alias is ambiguous, the following error occurs:

Error: MAPI MapiSend Failed: 21



WORKAROUND
Make sure that the mailbox aliases for the sender and the recipient are not ambiguous.

To test for ambiguity of names, perform the following steps:


 * 1) Type the recipient's (or sender's) name in the To box of a Microsoft Outlook or Exchange Client standard Send form.
 * 2) Click the To button or use the CTRL+K keystroke to see if the names are immediately resolved. If they are resolved without any prompting, they are not ambiguous.



MORE INFORMATION
The MapiSend.exe is a Resource Kit utility that allows a user to send messages with optional file attachments through Microsoft Exchange Server from a Windows NT or Windows 95 command prompt.

NOTE: MapiSend.exe was formerly known as the Command-Line Mail Sender Tool (Sendmail.exe). This program is also available in the Microsoft Mail Resource Kit.
