Error code 451?
I do not know ... I went to google and I found the following:
SMTP error 451 indicates when the user exceeds the limits set on the email server for sending emails. The email server will not allow the user to send more emails than the limits set on the email server; these limits are set as daily or hourly limits to restrict abusive behavior.
----------------
..and it is the only I found about it sorry.

Hello,
Email notifications stopped working after MT5 platform update to build 3815.
I am receiving error message "connect to smtp.office365.com:587" failed.
It was working perfectly on previous versions of MT5.
Is that a bug?
