Supported platforms and requirements

CodeTwo Exchange Rules is designed to work with five versions of Exchange Servers: 2007, 2010, 2013, 2016 and 2019. There are two main components that have to be installed. Their requirements differ slightly from each other. Study the description and table below to get an overview of supported systems and requirements enabling its smooth and uninterrupted operation. There is no need to install anything on end-users machines, the software runs server-side.

Exchange Rules Service is a set of services (Transport Agent, Exchange Rules Service, Attendant Service, Sent Items Update Service) responsible for processing rules and settings defined within the Administration Panel and applying them to messages traveling through the Exchange Server.

Administration Panel is the management console of the program used for configuration of rules and other settings associated with the program's operation. The Administration Panel handles the settings to Exchange Rules Service, which is responsible for processing them.

Notes and warnings


  1. ^ The program can also be installed on the Server Core version of Windows Server. Learn more
  2. ^ Be aware that Internet Explorer 9 is not available for Windows XP/2003 but it is required by CodeTwo software. You may experience some minor issues when editing signature templates on a machine without IE9 installed.
  3. ^ If you are running Exchange 2013 CU11, please consult this KB article before installing the program.
  4. ^ When installing on Windows Server 2016, make sure your operating system includes the latest updates. Learn more.
It is impossible to install program components using Group Policy Object (GPO) or other unattended or remote deployment method. The installation has to be performed manually on each machine.
Linked mailboxes are supported; however, Active Directory data such as AD user properties and AD group membership is taken from the domain controller of the environment in which the Exchange Server and CodeTwo services are installed.
Encrypted and digitally signed emails are processed if the S/MIME or Active Directory Rights Management Services (AD RMS) standard is used. Others, such as PGP or OpenPGP (e.g. GPG) are not yet supported.
Size on disk after installation: When both the Administration Panel and the Exchange Rules Service are installed, the installation size on your disk is similar to the size of the installation file (see the Download page for details). Installation of additional components (such as .NET) might be required - these components usually require less than 100 MB of available disk space.
