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 188.8.131.52, 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:
Download the latest version of the applicable Permissions Wizard:
Run the Permissions Wizard on the existing installation, directory services, and message store services accounts. Refer to the Permissions Wizard help for more information.
