The voice message form adds a dedicated toolbar to Microsoft Outlook. Use this toolbar to play voice messages and call the email sender from Outlook. To integrate Messaging with Outlook, you must:
Verify that your Exchange server has the forms folders.
If the Exchange server does not have the forms folders, you must create the forms folders.
Use Outlook to add the voice message forms to the forms folders on your Exchange server.
You can add the form to the system folder on any of the following Exchange servers:
Exchange 2007
Exchange 2010
System folders are hidden folders for internal Exchange System Management. In large organizations with specialized administration roles, the Exchange administrator completes these tasks.
