We have recently begun experiencing a communication error when trying to send emails via Comet to O365. The message "unexpected error 29 encountered" displays. After acknowledging the message several times, the email(s) are sent. Is this due to a change made by Microsoft to O365.

Email.ini:

server = smtp.office365.com 587
user = billing@metroelectricsupply.com
password = M*********
tls=true

Also, I have been notified by the company that provides our email support that within the next 9 to 12 months Microsoft will switch from legacy authentication to modern authentication for all devices. Does anyone know if Comet will handle this?

Thanks
