Hello,
For the last few days some my incoming emails to my on site Exchange 2013 are being bounced back with the sender getting the following error.
A communication failure occurred during the delivery of this message. Please try to resend the message later. If the problem continues,
contact your email admin.<o:p></o:p>
mailservername.domain name.com gave this error:
command not implemented
Are there any log files in Exchange that I can enable to see why they are being bounced?
Any suggestions will eb very much appreciated.
Thank You,
Victor.<o:p></o:p>
