Overview Microsoft Outlook Web Access 2007 (OWA 2007) Microsoft Outlook Web Access 2007 (OWA 2007) is a built-in component of the Exchange Server 2007 system that offers rich support for many of Exchange Server’s capabilities in a Web-based client. OWA 2007 provides access to a user’s mailbox from any desktop connected to the Internet and provides the full set of Outlook features through Microsoft Internet Explorer (IE).
PAGE 3
OWA Extension on Exchange 2007 Architecture The OWA Extension architecture is based upon Exchange Web services, which are an integral part of the Exchange 2007 architecture. OWA Extension is a Web Service Client Application that is installed on the customer’s Exchange 2007 server with a Client Access Server (CAS) role (described later in this document).
PAGE 4
Microsoft Exchange 2007 Server with CAS Role OWA 2007 and OWA Extension are supported for Exchange Server 2007 SP1 with Client Access Server (CAS) Role on both Windows Server 2003 and 2008. The CAS Role basically accepts connections from a variety of clients to allow them access to the Exchange Server infrastructure. To some extent, the CAS Role shares some similarities with the old front-end (FE) servers in Exchange 2000 and 2003.
PAGE 5
OWA Extension High-Level Workflow This section describes the OWA Extension workflow. When a user opens any mail in OWA 2007, it first checks the registry.xml file for any custom message class definitions (see below). If a match is found, control is redirected to the custom page where tombstone retrieval is handled. In the custom page, the mail item’s DocRef is read and a DocRef Document Retrieval URL is constructed with the DocRef value along with values provided in web.config.
PAGE 6
OWA Extension Supported Configurations The following is a list of Exchange 2007 configurations which are supported with OWA Extension: • • • • • Exchange 2007 CAS server + Exchange 2007 Mailbox server Exchange 2007 CAS server + Multiple Exchange 2007 Mailbox servers Exchange 2007 CAS, Mailbox server + Exchange 2007 Mailbox server Exchange 2007 CAS, Mailbox server + Multiple Exchange 2007 Mailbox servers Multiple Exchange 2007 CAS servers + Multiple Exchange 2007 Mailbox servers Unsupported Configurations

OWA Premium has the look and feel of Microsoft Outlook and uses extensions that are only available in Microsoft Internet Explorer. As such, OWA Extension is not supported on browsers such as Firefox or Netscape navigator. For Microsoft Exchange Server 2007, OWA 2007 Premium is required to retrieve tombstoned messages with OWA Extension. For Microsoft Exchange Server 2003, HP also strongly recommends the use of OWA Premium. Dependencies The OWA Extension application depends on the .NET framework 2.
PAGE 8
• Configuration File – The settings used by OWA Extension are defined in the file web.config, which defines the IAP URLs, Exchange Server, and Domain Name and directory information. • dll Files – The dll files required for the application are in stored the folder: :\Program Files\Microsoft\Exchange Server\ClientAccess\Owa\Bin • Customization Files – The files “PERSISTMailItem.ico” (an image file) and “UIExtensions.xml” (a configuration file) are the icon settings for IPM.Note.
PAGE 9
Installing and Configuring OWA Extension To install OWA Extension, the following must happen: 1. Microsoft Exchange Server 2007 (SP1, Update Rollout 5 or later) must be installed and configured with a CAS role (can also be a Mailbox Server) or on a standalone CAS server. 2. OWA 2007 must be installed and functional before installing OWA Extension. 3.
PAGE 10
Running OWA Extension on Exchange 2007 Setup When you first run HPOwaSetup.exe, you will see one field marked “Installed” with a green check mark and the rest of the fields marked as “Not Installed” with red X’s next to them. This indicates that OWA Extension has not been installed.
PAGE 11
OWA Extension on Exchange 2007 Setup Completion After OWA Extension is installed successfully, you will see green “Installed” check marks next to each field. Figure 4.
PAGE 12
Connecting to OWA 2007 Client to Verify Installation After the installation completes, connect to an OWA Client via Internet Explorer and sign on as an Exchange mailbox user. Verify that all EAsE-archived messages are marked with tombstones in the user’s mailbox. Then open a tombstoned message (and its attachments if they exist) to confirm that the archived message is retrievable. Figure 5. Opening OWA 2007 Client in Internet Explorer Figure 6.
PAGE 13
OWA 2003 versus OWA 2007 Tombstones Note that under OWA 2003, a user does not see tombstone icons when initially logging into OWA to view his or her mailbox. The user must manually open each message individually before they can potentially see a tombstone on the upper left corner of the message indicating that the message has been archived by EAsE and IAP. With OWA 2007, a user sees tombstone icons immediately when logging into OWA to view his or her mailbox.
