EXCHANGE SERVER 5.5 NO LONGER SUPPORTED FOR NEW INSTALLATIONS
As of January 1, 2006, Microsoft Exchange Server 5.5 is no longer allowed as the message store for new installations of the Cisco Unity system. This directive applies to all versions of the Cisco Unity system, and to both unified messaging and voice messaging configurations. If a customer installs a new Cisco Unity system on or after that date and configures the Cisco Unity system to use Exchange 5.5 as the message store, The Cisco® Technical Assistance Center (TAC) will not support the system until the customer has upgraded to Exchange Server 2000 or 2003.
Cisco Unity software is no longer shipped with the Voice Mail Run-Time Edition of Exchange Server Version 5.5.
FOR CISCO UNITY 4.2 AND LATER, MICROSOFT EXCHANGE SERVER 5.5 NO LONGER SUPPORTED FOR NEW INSTALLATIONS OR UPGRADES
Beginning with Cisco Unity 4.2, installations and upgrades will fail when Exchange 5.5 is the message store. Before you can upgrade to Cisco Unity 4.2, you must upgrade to Exchange 2003 or Exchange 2000.
EXCHANGE SERVER 5.5 SUPPORT FOR EXISTING INSTALLATIONS CONTINUES TO THE EXTENT POSSIBLE
To the extent possible, Cisco will continue to support Exchange 5.5 as a message store for existing Cisco Unity systems for as long as those Cisco Unity systems are supported. However, if Cisco encounters a problem with Exchange 5.5 that it cannot resolve, the company will require the customer to upgrade to Exchange 2003 or Exchange 2000.
INSTALLATION OPTIONS
Cisco will continue to ship the Voice Mail Run-Time Edition of Exchange 2000 Enterprise Server. Customers who want to install the Cisco Unity system in a voice messaging configuration can use this version of Exchange for the message store.
Customers who want to install the Cisco Unity system in a unified messaging configuration have two options:
• Upgrade to Exchange 2003 or Exchange 2000 before installing the Cisco Unity system.
• Set up a mixed-messaging environment, install at least one Exchange 2003 or Exchange 2000 server, and move the mailboxes for users who will be Cisco Unity subscribers from Exchange 5.5 to Exchange 2003 or Exchange 2000.
CISCO UNITY DOCUMENTATION INCLUDES INFORMATION ABOUT UPGRADING FROM MICROSOFT EXCHANGE 5.5 TO EXCHANGE 2003 OR EXCHANGE 2000
