Hi, We have problem with MSExchange 2010 OWA. When we try to open up OWA, it gives error message "Outlook Web App didn't initialize......". I check Event Viewer, and there is some error with OWA configuration. So I do some research, and find out that I have to configure using Exchange management shell. When I type the command "set-owavirtualdirectory -identity "server1\owa (default web site)" -formsauthentication $true", it gives me error message "the operation couldn't be performed because object 'server1\owa (default web site)' couldn't be found on 'dc-server.mycompany.com' + categoryinfo : notspecified:(0:int32) [set-owavirtualdirectory], managementobjectnotfoundexception + fullyqualifiederrorid : c8084e,microsoft.exchange.management.systemconfigurationtask.setowavirtualdirectory" I tried changing default domain controller using set-adserversetting to another domain controller, but the same error message keeps popping as the result. Please advise, thanks a lot. Arief
