EV9.0 / Exchange2003 - OWA not loading EV items after email-domain change
scenario: Exchange 2003 (1x FrontEnd Server, 2x BackEnd servers), Enterprise Vault 9.0.4 server
we recently changed our corporate email (from eg. abc.com to xyz.com) this was reflected on the recipient policies on Exchange, with new xyc.com policy added and old abc.com references removed (also removed using IIS Metabse explorer on Exchange server). So technically, abc.com does not exist on our exchange organisation anymore.
Since this change, the OWA login for EV does not show the EV forms/toolbars nor does it open vaulted emails (IN OWA the emails which have been vaulted still show as the EV shortcut but when double clicking to open those email items, a new web page opens with no content - absolutely blank). This is also the case when i login directly into OWA through the backend server e.g. https://localhost/exchange
On the backend servers, I've reran the MakeEVServersTxt.wsf to make the evservers.txt file, and then ran the Symantec Enterprise Vault OWA 2003 Extensions.msi installer, then after that was done i ran the 'OWA and RPC' extension configuration. These all completed without errors.
(EDIT - FYI these vaulted emails open fine in outlook)
