Hi, run the command Set-DistributionGroup -Identity groupname -RequireSenderAuthenticationEnabled :$false If you want to do the same for all your distribution groups, run the shell command Get-DistributionGroup | Set-DistributionGroup -RequireSenderAuthenticationEnabled :$false I hope this will help you.

Dear, Thnks for your replay, But the mails are not even reched in edge.& where shall i run this in edge or in mail server -shefe

Hi, If mails are not landing on your Edge box than check your firewall settings I think your firewall is the real problem. Try to open all ports which exchange needs to run. Regards.

Dear Shafaquat Ali, plese find the events on edge, plese give me guides. -------------------------------------------------------------------------------------------------------------------------- 1. An internal transport certificate expired. Thumbprint:EEF4F2218C58FF2E6117BC1642B3FC28E020E8F3 For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. ------------------------------------------------------------------------------------------------------------------------ 2. Microsoft Exchange couldn't find a certificate that contains the domain name ez__.e__a.local in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector edgesync - default-first-site-name to internet with a FQDN parameter of ez__.e__a.local If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key.
