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 :

Citrix Session Printers Registry Key Location


Session printers created via policy in Citrix XenApp are considered local printers. As such they are in the registry key that is common for local printer definitions. That registry key location on Windows 2008 R2 is :


Problem with session printers such as additional printers appearing in the user's list of available printers while in a session, most often is a result of driver corruption. Once the corrupt driver has been fixed or removed, you may have printers still showing up in user sessions that do not belong.

One of the things you can check is the key in the registry where the session printers are defined.
For stuck printers, as option to get rid of them is often to delete the users profile but that's not always the best option so removing the session printers defined for that user can be done through the registry. Be cautious when removing but when there are no users logged into the Cirix Xenapp server, there should be no session printers defined.
