Hi,
Recently I have migrated from windows SBS 2003 to windows SBS 2011. So, it has MS-Exchange 2010. It is working for every email but it is creating error for one domain. If i try to send email to anyuser@commandercentre.com it shows:
The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.
Diagnostic information for administrators:
Generating server: CMDCNTRSVR.CCSW.local
#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ##
But we can receive email from anyuser@commandercentre.com but we can't send.
The email address is not invalid. I can send email from yahoo/hotmail. Its not autocomplete issue of outlook 2010.
Can anyone help me to rectify the issue.
