When installing Enabling Technologies etcMWI software it is configured for the customers Exchange environment at the time of the install.  We all know things change, and change is good!  However, when you change your Exchange environment, it has to be updated to support etcMWI.

etcMWI takes advantage of the Exchange impersonation capability to monitor a user’s mailbox for new unread voicemails.  This impersonation has to be applied to all Exchange 2007 mailbox and client access servers and mailbox databases.  So when you add any of these servers or databases to your existing Exchange organization you must apply the impersonation to these new resources.

This applies to all versions of etcMWI and Exchange.  Instructions on how to accomplish this can be found in the etcMWI Installation Guide provided to you.  It is detailed early on in the document and an easy to use Powershell script is provided in the Appendix.  If you need help, contact Enabling Technologies Tech Support
