We use the prtg network monitor. I want to to configure notification for a distribution group email address. When the prtg uses a user address the test email is sent, but when the email address is a distribution group on o365 email is not received by O365. When I use a powershell script on the prtg server , a email is received by o365. the prtg log does not show any errors. The name of group is aaaaaaaaaaaaaaaaaaaaaaaa@bbbb.bb.cc. ( a long name) So, the problem is in the prtg software, because an email can be recived from a powershell script. May I get any help?

Regards Wald

Can you check the Distribution Group in Office 365 ?. You can control, if a Distribution list is reachable from outside (Default yes, but maybe the powershell script is authenticating against the SMTP-Server. You can also install Netmon/Wireshark and track for "tcp.port == 25" and see the outgoing Connections to Office 365 and what happens.

Is the group enabled to receive mails only from authenticated users?
