relay not allowing send email externally

Need help configuring the relay for internal users to send external email.
Exchange 2010x64 server - up to date as is W2008R2.

Email sent externally bounces back with

#550 4.4.7 QUEUE.Expired; message expired ##

Telnet test told me,

550 5.7.1 Unable to relay

PWS3v2

Internal email works and can receive external (outside domain) email, but cannot send email out from the domain.

Need help configuring Exchange 2010 relay for internal users to send mail externally.

Single internal Exchange 2010 server. Not using edge transport. Just using Outlook 2010 internally. No external devices or servers.
