More Info for Email Admins
Status code: 550 4.4.7

This problem may have occurred for the following reasons: The recipient domain may be overly aggressive about blocking messages from Office 365 or messages it suspects are spam, it may be experiencing networking problems, or its MX records are out of date or set up incorrectly.

Review the reported error - Check the Reported error below to help determine why the recipient's email server refused the connection. For example, the error SuspiciousRemoteServerError often indicates the recipient's firewall SMTP fixup setting or other firewall settings are preventing the SMTP protocol negotiation from succeeding.

Contact the recipient's email admin - Most often the recipient's email admin is the only one who can fix this. Contact the recipient's email admin and give them the Original Message Details and Error Details found below.
