I have been scanning to email for years. I started receiving"Transmission has failed. To check the current status, press [Scanned Files Status]."After checking the error I found this:"Authentication with the destination has failed. Check settings. To check the current status, press [Scanned Files Status]."
I have changed the password for the username/email smtp server and entered the new password on the machine and rebooted the machine. This worked for about an hour. Then after trying to send my 10th scan it stopped working and gave me the same error messages.
