[Update]: This article was first published on September 7, 2015. It was updated to reflect the current UI of the program and the latest developments in Exchange Server.
While some people think that emoji are a must in everyday email communication, others see them as unprofessional and juvenile. Consequently, some companies want to get rid of emoticons to retain a more formal style. Unfortunately, Exchange Server does not provide sufficient tools to filter out or replace unwanted strings of characters. The only way through is to use a third-party solution.
CodeTwo Exchange Rules Pro is a centrally managed tool that allows you to control email flow on on-premises Exchange. Its main service is deployed directly on the server’s communication pipeline and requires only a few touches from an administrator to be configured and start working. This feature-rich toolbox allows users to swiftly modify incoming and outgoing messages by simply setting up appropriate rules. Creating a rule to eliminate emoji from your Exchange email is a piece of cake.
Exchange 2007 was the first edition of Microsoft’s messaging platform to introduce Hub Transport rules and with them a built-in append disclaimer action. The options available in this action are very basic, the most important limitation being lack of support for dynamic Active Directory fields (see this article for more). Due to this, the action can only be used for creating automatic disclaimers (legal, financial, etc.) and general company signatures without users’ details.
Once you have the Hub Transport role installed on your Exchange 2007 server you can start working on automatic disclaimers for your organization.
Steps to set up automatic email signatures and disclaimers on Exchange 2007:
Open the Exchange Management Console, expand Organization Configuration, select Hub Transport, click the Transport Rules tab in the middle Result Pane and in the Actions Pane on the right click New Transport Rule… (Fig. 1). This will trigger the New Transport Rule creation wizard.
