Outlook Web App didn't initialize - Exchange 2010

Desktops, Servers, and Networks, oh MY!


Outlook Web App didn't initialize - Exchange 2010


OWA version: 14.1.355.2



Exchange 2010 Outlook Web App loads the login form page for users of OWA but after login an error page is displayed that displays an error indicating that Outloo kWeb App cannot initialize. This is an authentication issue.

In the case of the blogged server situation. The SSL cert was purchased form digicert.com and pplied successfully. The problem was the settings in IIS and in Exchange management console for client access of outlook web access (woops, outlook web app) were not "matching".

Server configuration > client access > owa properties > Authentication Tab

Select Use Forms Based, User name only. Enter your logon domain (your local internal Active Directory domain).

Next, in IIS7, go to the following spot in the tree under Default Website and set the authentication like the following image shows.



That's all I had to do on my Exchange 2010 server to get past the OWA error message after login in of :
