After you install Microsoft security update MS06-019 - Vulnerability in Microsoft Exchange Could Allow Remote Code Execution or MS07-026 - Vulnerabilities in Microsoft Exchange Could Allow Remote Code Execution, Cisco Unity cannot deliver voice messages to subscribers when all of these statements are true:

  • The Cisco Unity server runs Cisco Unity version 4.0(1) through 4.1(1).

    Note: Earlier and later versions are not affected.

  • The Exchange mailboxes for the affected subscribers are homed either in Exchange 2003 or Exchange 2000.

  • The Active Directory accounts associated with the affected subscribers belong to one or more administrative groups. For example, Enterprise Admins, Schema Admins, Domain Admins, or Administrators.

  • The Permissions Wizard that was last run to grant permissions to the installation and services accounts is older than version, dated September 8, 2004 (9/8/04).

    Note: The version of Permissions Wizard currently installed on the Cisco Unity server is not necessarily the version that was used to set permissions. When Cisco Unity is upgraded, a new version of Permissions Wizard is automatically installed.


Complete these steps to resolve this issue:

  1. Download the latest version of the applicable Permissions Wizard:

  2. Run the Permissions Wizard on the existing installation, directory services, and message store services accounts. Refer to the Permissions Wizard help for more information.
