Hi,
We have an very strange issue with Exchange 2013 (CU8, issue was the same with CU7) and receive connector on CAS. We have 1 CAS server,1 Edge and 2 Mailbox servers. This started to happen when 2010 was uninstalles/removed. Everything worked before 2010 was removed.
We have a seperate Receive connector for mail relay from scanner/software etc. If we try to send to external addresses (user@external.com) we got this response:
"451 4.7.0 Temporary server error. Please try again later. PRX1"
If we send with internal address (user@internal.com) its works. Anonymous access is configured. The strange thing is that when we test and send a test-message with both internal and external address (user@internal.com; user@external.com), both is delivered OK.
Used this commands to test:
This command works:
Send-MailMessage -From test@internal.com -To user@external.com,user@internal.com -Subject TestMail -SmtpServer serverip
This command gives errorcode:
Send-MailMessage -From test@internal.com -To user@external.com -Subject TestMail -SmtpServer serverip
Send-MailMessage : Error in processing. The server response was: 4.7.0 Temporary server error. Please try again later.
PRX1

We have created an case with Microsoft, but the response from MS is very bad/nothing.
Anyone that have seen this behavior?
Thanks
