I've been using this metho to send email from stored procedures now for months even years.
So much so that I've forgotten how I actaully set it up.
I know someone told me how.
As I said the process worked fine up until today.
I am now getting an error message in the failures table
Failed at sp_OAMethod Send
The server rejected the sender address. The server response was: 530 5.7.1 Client was not authenticated
Does anyone know what might have changed.
I am not the system administrator. We have an external Company who may have changed something.
Can anyone help
