Hi Guys, We can't seeem to access to OWA and we are getting the error message dislpayed on the browser below. Outlook Web Access did not initialize. An event has been logged so that the system administrator can resolve the issue. Please contact your techinical support for your organization. Procedures done: 1. The IUSR_Servername and IWAM_servername accounts' passwords were corrupted or has been changed and out of synchronizing between AD & IIS. Reset these accounts passwords in both ADUC and IIS. Then run IISRESET to restart IIS. 2. The OWA server may have difficulty to communicate with the DC. Adding the iusr_servername & iwam_servername to the OWA server local users group may help. 3. You may receive this error after upgrading the system or update security patches. Enabling and disabling the Integrated Authentication in the IIS. Then run IISRESET.
