# Exclaimer

### Introduction

Exclaimer is a Microsoft Office 365, Exchange Server and G Suite solution for email signatures, archiving, email utilities & more.  

It's possible to have Exclaimer and SecuMailer cooperate together to enjoy the benefits of both solutions. This appendix contains instructions for the proper setup of Exclaimer together with SecuMailer.

### Exchange Admin Center 

Please open a browser and provide the URL for your Exchange Admin Center.

In EAC select `mail flow` in the main menu and subsequently select `rules` from the context menu. In the rules overview move the Exclaimer rule above the SecuMailer rule(s) using the up arrow in the rules menu (see screenshot below).

### Mail flow rule

After you've moved the Exclaimer rule above the SecuMailer rule, select the edit option to change the SecuMailer rule(s).

Change the first condition `Apply this rule if...` , add a condition by selecting `A message header...` from the drop down and select `includes any of these words...`

Click on `Enter text...` , fill in **X-ExclaimerHostedSignatures-MessageProcessed** and click on `OK`. Click on `Enter words...`, fill in **true**, click on the `+` symbol and click on OK. See below for an example.

Click on `Save` to store the change.

This change ensures that O365 / Exchange checks that the Exclaimer processing has completed successfully before sending the email to SecuMailer for further processing.
