Login problems on Exchange 2007 OWA
If you have two separate Exchange Server 2007 mailbox servers, and users in one mailbox server can login to Outlook Web Access using your Client Access Server, while the users on the second mailbox server cannot log in to Outlook Web Access using the same Client Access Servers, the following might help.
This issue is seen if the mailbox server is running Exchange Server 2007 SP1 on Windows Server 2008. From Server Manager, open Web Server (IIS). Make sure the following Role services are added:
Under Application Development, select the following:
- ASP.NET
- .Net Extensibility
- ASP
- ISAPI Extensions
- ISAPI Filters
- Server Side Includes
- .NET environment
Under Security, select the following:
- Basic authentication
- Windows Authentication
Do an IISRESET /noforce.
You should be able to login now. If you can’t try logging in using the domain\username format, even if you chose the option for ‘user name only’ on your Client Access Server. If you are able to log in with domain\username and not just username, and you have enabled ‘username’ only option under Forms based Authentication on your Client Access Servers, try the following.
On the IIS of your Exchange Server 2007 mailbox server, navigate to the /exchange virtual directory, open Authentication, and change the properties for Basic Authentication and enter a "\" without the quotes for the Default Domain.

hey thanks this resolved my OWA access issues
i was missing some iis role services
colleague of mine installed and didnt do a proper check of the pre-reqs
Hi Shijaz,
I am currently working on Exchange 2007. I am running into a same problem with users that are trying to access OWA using the https://mycompany.com/exchange virtual directory. I have setup Basic auth on all my virtual directories on IIS and set them with correct domain. When a 2003 mailbox user authenticates they are presented with their 2003 OWA mailbox without any problems. If a 2007 mailbox user accesses https://mycompany.coml/exchange and use only their user name “john” they are prompted with “The user name or password that you entered is not valid. Try entering it again.”. If I use “mycompany\john” they are proxied to the /OWA virtual directory correctly and are presented with their OWA 2007 Mailbox as they should be. This is going to be a huge headache if I cannot have my users access the same URL. Here are my environment details
O/S – Windows 2008 Enterprise edition SP2
MS Exchange 2007 SP3 (CAS and Mailbox roles are installed on different machine)
IIS-7
Can you please share your ideas on how to resolve this?
Thanks in advance.
Your the man Shijaz! Thanks, it helped me out =)
