Before you install the Enterprise Vault OWA Extensions, ensure that you have completed the prerequisite tasks.

See Configuring Enterprise Vault access for OWA users.

Enterprise Vault OWA 2010 Extensions are located in the folder, Symantec Enterprise Vault version\OWA Extensions\OWA 2010 Extensions on the Enterprise Vault release media.

A ReadMeFirst file is located in the folder, Symantec Enterprise Vault version. Before you install the extensions, ensure that you check this file for details of any last-minute changes.

Follow the instructions in this section to install the extensions interactively. Alternatively, the OWA Extensions can be deployed silently using an MSI command line, or using an Active Directory Group Policy Object (GPO) to install to a particular Organizational Unit (OU).

To enable logging for the installation process, either set up the logging policy for Windows Installer on the server, or run the installer using the msiexec command line and include the logging option:

/l*v log_filename
