The domain name is not consistently authoritative or nonauthoritative among recipient policies
Topic Last Modified: 2009-12-11
The Microsoft Exchange Server Best Practices Analyzer examines the recipient policies that are configured in the Exchange organization. During this examination, the Best Practices Analyzer determines whether the SMTP domains that are specified in each e-mail address policy are consistently marked as authoritative or nonauthoritative across all the recipient policies. If the tool detects that one or more SMTP domains are inconsistently marked as authoritative or nonauthoritative, the following error message is generated:
The domain '<SMTP-Domain>' is configured authoritative or non-authoritative inconsistently among multiple recipient policies.
Having one or more SMTP domains inconsistently marked as authoritative or nonauthoritative may cause mail flow issues when you install Microsoft Exchange Server 2007 or Exchange Server 2010 or when you prepare the domain for Exchange 2007 or Exchange 2010.
When you install the first Exchange 2007 or Exchange 2010 server role, or when you prepare the domain for Exchange 2007 or Exchange 2010, the Setup program runs the Setup /PrepareAD command. This command parses the recipient policies in the organization. If the Setup program detects SMTP domains that are marked as both authoritative and nonauthoritative, the program modifies the affected recipient policy or policies. In this situation, the Setup /PrepareAD operation marks the inconsistent SMTP domains as nonauthoritative. If Internet Information Services (IIS) is not restarted after running Setup /PrepareAD, e-mail messages may remain in the mail delivery queues. Also, if an inconsistently marked SMTP domain was intended to be authoritative for the forest, mail flow may be interrupted.
To address this issue, examine the recipient policies in Exchange System Manager to verify that each SMTP domain is consistently marked as authoritative or nonauthoritative in the forest.
