Outlook Web App didn't initialize - Exchange 2010

Outlook Web App didn't initialize.

If the problem continues, please contact your helpdesk.

Request Url: https://your-server-name.domain:443/owa/auth/error.aspx
User host address: ::1
OWA version: 14.1.355.2

As you will see from the posted images this Exchange 2010 server was no lab.The was a real situation.  It was not in a sterile lab with no real issues or customer waiting to use the money they lspend on new technology and hardware. How it got to this unknown but the resolution to this problem took a little time and is solid.
This Exchange 2010 server was purchased and setup for a migration from Exchange 2003 to Exchange 2010. It was not setup for demo or lab purposes. It was setup with intend and goal to be a real Exchange server for a migration from Exchange 2003 and getting put into production. But Outlook Web App was not working and this customer is going to need it. Hope this post helps someone out, Cheers!

The error message in OWA occured after the login. The OWA login page displayed okay but after the login, the following error occurred.

This is most like due to an improper security setting for the owaa virtual directoy. NOT the file system owa directory under the exchange program folder.


The setting I have for owa to work are:

From within Exchange 2010 management Console

From within  IIS:

The above settings solved the error. This site had a valid cert. You don;t need one for this problem to be solved but be aware that in IIs you'll have to uncheck the box that says require SSL cert.
Cert erros are totally unrelated to this. This is strictly an authentication issue within Exchange 2010 OWA and IIS 7.

You can also use the following shell commands to test connectivity . 

Exchange management shell :

Create new exchange 2010 test user account . Run the folloing from the scripts\ directory in the exchnage program folders. Use the exchange command shell with elevated privlages to create the test account if you don;t have one already. .




output display was the following: 

The test couldn't sign in to Outlook Web App due to an authentication failure.

The error above was displayed as output prior to the fixes noted earlier i nthis post.

Thanks, I've been working with this outlook web app problem for several hours. It's my first exchange 2010 installation. I have exchange 2010 with service pack 1 on 2008 R2 server. I could not get OWA to work. I applied the SSL certificate and that went well. But this error with exchange 2010 and outlook web app was just not going away no matter what I tried in IIS7 (which I am also kinda new to) or through the exchange management console. I had removed and re-added the virtual directories and exchange services so many times. I even recreated the directory structure for those exchange 2010 services but that did not help solve the problem either. I like the test commands too. I created an exchange test account as per your instructions. Thanks for that too. It's a faster test than using owa.
Just up arrow in the command console shell instead of retyping information in the address bar or having to retype password or user accounts.
