DescriptionExchange Server Mailbox Manager failed to send the following message:

Subject: The Microsoft Exchange Server Mailbox Manager on Server Name completed processing successfully.

Recipient: username@name.com

Error: c1050000
Event InformationHere is an information from a newsgroup post:
In Exchange System Managernavigate down to Server Name\Protocols\SMTP and
then right click on the Default SMTP Virtual Server and then click on
Properties. Click on the Access tab and then click on the Authentication
button. Make sure that Anonymous is selected here. If not, select the
checkbox and then click on OK, OK. Restart the SMTP Service.

The reason for this is because the Mailbox Manager process uses CDO to
submit the email and the server must allow Anonymous connections so that the
email can be sent.
