Explanation

This Error event indicates that there is no default authoritative domain, or that the authoritative domain name is empty.

Accepted domains are any Simple Mail Transfer Protocol (SMTP) namespace for which a Microsoft Exchange organization sends and receives e-mail. Accepted domains include those domains for which the Exchange organization is authoritative. An Exchange organization is authoritative when it handles mail delivery for recipients in the accepted domain. By default, one accepted domain exists and is configured as authoritative for the Exchange organization during installation.

For more information, see Understanding Accepted Domains.
