ISA 2006 SP1 Configuration with Exchange 2010

While ISA 2006 SP1 includes a Client Access Web Publishing Wizard for both Exchange 2003 and Exchange 2007, the wizard does not have any knowledge of Exchange 2010. Exchange 2010 includes the following changes with respect to its URLs and virtual directories:

• Exchange 2010 Client Access Servers (CAS) no longer utilize the /exchweb virtual directory.
• Exchange 2010 CAS no longer utilizes the /unifiedmessaging virtual directory.
• Exchange 2010 CAS provides a new solution for managing end user configuration (e.g. Unified Messaging settings), end user self-service (e.g. message tracking), and organization-specific activities (e.g. records discovery), known as the Exchange Control Panel. This service is provided via the /ecp virtual directory and is accessible directly or through Outlook Web Access.
• Exchange 2010 CAS does not render data from legacy mailboxes. Instead, depending on the protocol and/or client, Exchange 2010 CAS will either proxy, redirect, or provide direct access to the appropriate version of Exchange (Exchange 2003 Front-End, Exchange 2007 CAS, or Exchange 2003/2007 Mailbox). Redirected clients access their information via a new namespace, legacy.contoso.com. For more information, please see the post entitled, Transitioning Client Access to Exchange 2010.

As a result of these changes, certain modifications must be made to the rules created by the Client Access Web Publishing Wizard to support Exchange 2010. This article, the final one in my upgrade series, will discuss how to configure ISA 2006 SP1 as part of your deployment of Exchange 2010 in your existing Exchange 2003 or Exchange 2007 environments so that you may successfully allow your clients to connect to both Exchange versions.

Note: For more information on the detailed steps required to support coexistence process see my first blog article in the series, TechNet, or within the Deployment Assistant.

While this article will not cover every scenario possible (e.g. specifics on each authentication solution), it will provide basic steps that you can follow to ensure you have a successful deployment.

Archiving and Retention

As the volume of e-mail continues to grow within organizations, the need to systematically archive this information has become a growing priority. Archiving can provide users a better e-mail experience by making space in a user’s mailbox, which can result in improved performance. Archiving also helps the organization to address compliance and legal electronic discovery requirements by making e-mail easy to manage and search. To address these needs, Exchange Server 2010 now features new archiving capabilities that combine with other enhanced mailbox management features, including advanced, multi-mailbox search, legal hold and granular retention polices to provide a comprehensive solution. Easy-to-use and deploy, this built-in functionality helps organizations reduce reliance on separate archiving solutions and simplify legal and compliance processes.

Functional Descriptions

Personal Archive: An additional mailbox associated with a user’s primary mailbox. It appears alongside the primary mailbox folders in Outlook. The user has direct access to e-mail within the archive just as they do to their primary mailbox. Users can drag and drop PST files into the Personal Archive, for easy online access – and efficient discovery by the organization. Users can also move e-mail items from the primary archive to the Personal Archive automatically, using Retention Polices, to reduce the size and improve the performance of the primary mailbox. In addition, users can search both their Personal Archive and primary mailbox simultaneously using Outlook.

Retention policies: These apply retention settings to specific items or folders in a mailbox. Policies are configured by the Exchange Administrator and are displayed inside each e-mail, with a header that states the applied policy and delete date. These headers make it easier for end users to identify when an e-mail is set to expire and apply a new expiration policy if the e-mail should be retained for a longer full stop. Administrators can also set a default policy that can move messages from the primary mailbox to the Archive automatically.

Multi-Mailbox Search: Multi-mailbox searches of mailbox items, including e-mail, attachments, calendar items, tasks, and contacts as well as IRM-protected files. Multi-mailbox search works simultaneously across both primary mailboxes and Personal Archives with an easy-to-use control panel. This enables authorised HR, legal and compliance users to perform searches without reliance on IT. For legal discovery purposes, mail located through a search can be copied and moved to a specified mailbox or external store, as defined by the administrator, for further investigation. Advanced filtering capabilities include: sender, receiver, expiry policy, message size, sent/receive date, cc/bcc, and regular expressions.

Legal Hold: Immediate preservation of a user’s deleted and edited mailbox items (e-mail, appointments, tasks, etc.) from both their primary mailbox and Personal Archive. Litigation Hold can be set on individual mailboxes or across the enterprise and includes an option that automatically alerts users that a hold has been placed on their mailbox.
