Hello, I have a problem with my send mail event, i'am making the destination users as destination of my email, i think that the k2 label is making troubles on the exchange server becaus i've got this message in the error logs :
Client does not have permission to submit mail to this server. The server response was : 5.7.3 Client does not have permission to submit mail to this server.
I think if i remove the "K2" label from the destination users exchange will recognise the users and send the mail correctly.
ow can i remove it????
