Exchange Rules Service

CodeTwo Exchange Rules Service is one of the two major components of the program. It consists of the set of components / services and is directly responsible for processing settings and rules yet applying them to messages traveling through the Exchange Server within the organization.

Once the setup of CodeTwo Exchange Rules is initiated it will install the necessary services pack responsible for its proper functioning:


Please note that all Exchange Rules Services installed on each Exchange Server are of equal rank. If there are several Administration Panels installed within the organization, their connection to Exchange Rules Services depends on the availability of a particular Service at the time the Administration Panel was started. Thanks to the real-time replication of settings between the Agents / Services, all the settings will be up-to-date at all times.

CodeTwo Exchange Rules Transport Agent

CodeTwo Exchange Rules Transport Agent is the core component of the program which handles the message traffic over to its dependent service called the Exchange Rules Service that is used to analyze if the message traveling through the Exchange Server meets the conditions defined within the rules. Once the analysis is completed, it is being sent back to the Agent that decides if to take the actions upon the message. The order the actions are applied to messages is based on the order of the corresponding rules on the list. Furthermore, the rules are processed from the top to the bottom of the list.

CodeTwo Exchange Rules Transport Agent is pinned up directly to the Exchange Transport Agent and cooperates with it while processing messages. Once the first Administration Panel of CodeTwo Exchange Rules is installed, it connects to the first available Exchange Rules Service.

No matter how many Exchange Rules Transport Agents along Exchange Rules Services were installed within your organization, it is always the first available one that is used by the Administration Panel. Additionally, this Agent instantly replicates any changes made within the Administration Panel on the rest of Exchange Rules Services so if it goes down, the other will be already up-to-date. The Agents communicate between themselves via Windows Communication Foundation framework.

CodeTwo Exchange Rules Sent Items Update

Sent Items Update is responsible for updating messages in the Sent Items folder that were previously processed by the Exchange Rules Transport Agent.
