This procedure is only applicable if you are upgrading an Enterprise Vault 8.0 system that uses the OWA 2007 Extensions.
The target server for
WebDav requests is set in the configuration file, Exchange installation
path\ClientAccess\Owa\Web.Config
, on the Exchange 2007
CAS server. If you changed the entry in
this file to specify a server other than localhost, then the change
is preserved when you upgrade the extensions.
Note that if you later repair the extensions in Add or Remove Programs, then the value of the entry is reset to the default value, "localhost".
