Hi there,<br />
<br />
After Exchange 2016 CU8 upgraded, I noted that a transport rule what I created for removing the message-ID not work at all. My previous exchange 2016 CU6 is working well with the transport rule to remove message-ID. Do you have any idea about this bug?<br />

Exchange 2016 CU8 not working transport rule of removing message-ID

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
