Exchange Considerations That Apply Only Exchange 2007

Chapter 4 Designing a Cisco Unity System with Exchange as the Message Store

Considerations for Customer-Provided Infrastructure

In a Voice Messaging configuration, to help prevent Exchange transaction logs from filling the hard disk, a wizard in Cisco Unity Setup prompts the installer to change the circular-logging setting for any message store in the forest for which circular logging is turned off. If the customer is using an Exchange-aware backup application to back up Exchange message stores and clear transaction logs, the installer can choose not to change the circular-logging setting.

Exchange Considerations That Apply Only Exchange 2007

Note the following Exchange 2007 considerations when a Cisco Unity implementation will use customer-provided Exchange 2007 infrastructure:

Exchange 2007 is supported as the message store only when Cisco Unity is configured as Unified Messaging.

The Cisco Unity Voice Connector for Microsoft Exchange, which is required for communicating with another voice-messaging system by using AMIS, the Cisco Unity Bridge, or VPIM, can only be installed on an Exchange 2000 or an Exchange 2003 server. A Voice Connector is not currently available for Exchange 2007. If the customer has already configured a pure Exchange 2007 environment, an Exchange 2000 or Exchange 2003 server cannot be added to the environment and, therefore, Cisco Unity functionality that requires the Voice Connector is not available.

Cisco Unity Mobile Message Access for BlackBerry is not supported for Exchange 2007.

Integrated messaging via IMAP with Exchange 2007 is supported when Cisco Unity voice messages are stored in Exchange 2000 or Exchange 2003.

With Exchange 2000 or Exchange 2003, you can store e-mail messages in one Exchange message store, store Cisco Unity voice messages in another message store, and view both types of messages in a Microsoft Outlook Inbox. In this configuration, known as integrated messaging, you:

Configure Outlook to use MAPI to communicate with the message store that contains e-mail (MAPI is required because the e-mail message store commonly also contains calendars and contacts).

Configure Outlook to use IMAP to communicate with the message store that contains Cisco Unity voice messages. (Outlook only supports one MAPI connection at a time.)

Enable Exchange rich-text format on Exchange servers, which converts IMAP to TNEF-encoded IMAP. (If you do not enable rich-text format, voice messages appear in the Outlook Inbox as e-mail messages, so ViewMail for Outlook is not available.)

Exchange 2007 does not support TNEF-encoded IMAP, but you can still use an integrated messaging configuration with Exchange 2007 if you store e-mail in Exchange 2007 and store Cisco Unity voice messages in Exchange 2000 or Exchange 2003.

For more information on Cisco Unity limitations when Exchange 2007 is the message store, see the subsection “Cisco Unity with Exchange: Exchange Server 2007” in the section “New and Changed Requirements and Support—Release 5.0(1)” in Release Notes for Cisco Unity Release 5.0(1) at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_release_notes_list.html.
