Good morning, I would like to ask about a mistake I have when I try to send an email from Mautic with my exchange mail.
I have my configuration with another smtp server as well
The test mail connection and send tests work correctly.
Then when I send an email to a contact it shows me the following error:
Failed to send to XXXX@XXXXX: Failed to authenticate on SMTP server with username “XXXXX@XXXXX” using 0 possible authenticators Log
data: ++ Starting Swift_Transport_EsmtpTransport <> EHLO 10.2.5.4 <> STARTTLS <> EHLO 10.2.5.4 << 250

Can someone help me solve this error
