Availability Migration You are here: Home / Tutorials / Exchange Server 2010 Outlook Web App Authentication SettingsExchange Server 2010 Outlook Web App Authentication Settings September 19, 2010 by Paul exchange 2010 owa not working Cunningham 97 Comments Outlook Web App (OWA) is the webmail interface for exchange 2013 owa integrated windows authentication Exchange Server 2010. Most of you will already be familiar with the acronym OWA from previous versions of exchange 2010 owa url Exchange Server where webmail was named Outlook Web Access. Outlook Web App is hosted on the Client Access Server role for Exchange Server 2010 and integrated with IIS 7. The https://social.technet.microsoft.com/Forums/exchange/en-US/8af88a6d-d986-40aa-9400-044974b683ed/owa-forms-based-authentication-failing?forum=exchange2010 OWA URL is typically something like this: https://webmail.mycompany.com/owa To connect to Outlook Web App users must authenticate first. The OWA virtual directory can be secured using different authentication settings depending on the network environment. Exchange Server 2010 Outlook Web App Authentication Types There are four authentication methods available for Exchange Server 2010 OWA. They are: Integrated Authentication - this allows domain http://exchangeserverpro.com/exchange-server-2010-outlook-web-app-authentication-settings/ users who are logged on to domain computers to automatically logon to Outlook Web App. This is useful for internal Outlook Web App access as it simplifies the logon process for domain users (they don't need to logon once to the computer and then a second time for OWA). However Integrated Authentication is not suitable for remote access by people using non-domain member computers, or people who are connecting via proxy servers. Basic Authentication - this uses the HTTP protocol to send the logon credentials to the server. Because the credentials are sent "in the clear" the use of SSL is highly recommended for securing them. Also, because Basic Authentication credentials can be cached in web browsers it is recommended to use an additional authentication factor (eg a one-time password from a token) to prevent unauthorized access from public kiosk computers using the cached credentials. Logon dialog box for Outlook Web App using Basic Authentication Digest Authentication - this method solves the problem with Basic Authentication where credentials are sent "in the clear" by sending a hashed password instead.

Creating your account only takes a few minutes. Join Now Bit of a long one but in summary - Users are unable to login to OWA/EWS http://english.rovermarinho.org/error-unexpected-error-occurred-owa-authentication/ and ECP This is the admin server for a small business of ~10 employees, it is a single physical machine installed with Windows Server Std 2012, and Exchange standard 2013. Recent history includes installation of a exchange 2010 hotfix to allow additional USB backup drives to be added individually - http://support.microsoft.com/kb/2833738 - following this and the reboot there were issues with access to EWS noticed by the boss's Mac, and by me getting into OWA. Login would work but you would be forwarded to an empty white page. ASP.NET warnings in the application event log : ASP.NET 4.0.30319.0 "Event message: An unhandled exception has occurred." I investigated this but exchange 2010 owa was unable to identify a particular fix, so with CU2 currently installed we upgraded with SP1 (aka CU4 after first removing CU2 due to an error in the SP1 upgrade). Following this OWA/ECP did not provide a login page - just an empty white page - no more ASP.NET errors were generated. Due to 3rd party transport agents running on this server (Trend AV) I had to apply this fix : http://support.microsoft.com/kb/2938053/en-us for email to flow out again. Someone pointed out to run updatecas.ps1 from the exchange bin directory, which I did : C:\Program Files\Microsoft\Exchange Server\V15\Bin>dir .\UpdateCas.ps1 But no improvement was seen.The virtual directories were then removed and recreated : Remove-OwaVirtualDirectory -Identity "adminsrv\owa (Default Web Site)" New-OwaVirtualDirectory -InternalUrl 'https://mail.domain.com/owa' -WebSiteName 'Default Web Site' Now OWA/ECP gives a login page but on login it simply fails with error :"The user name or password you entered isn't correct. Try entering it again." The password is NOT incorrect and has also been reset to confirm it is correct, I have tried with multiple accounts using different formats for the username : username DOMAIN\username DOMAIN.local\username I have tried different ways to access the server, from itself using multiple web browsers, and also client machines https://NETBIOS/owa https://FQDN/owa https://externalFQDN/owa All give the same err
Exchange by Rover Marinho Error - Unexpected error occurred OWA Authentication Error Scenario Scenario with two servers CAS (CAS01 and CAS02), where one server CAS01 this front with the internet (Internet Facing) in Site1, the other server CAS02 this in another Active Directory site the Site2. And effected seeking access address mail.rovermarinho.org in CAS01 is required to make this CAS server process Proxyng, redirecting the connection to the server CAS02, with the demonstration of the browser URL for external access mail.rovermarinho.org. When trying to accomplish this process, we received the error shown in the figure below: This error can be generated in many ways, but a common process for generating this error is when changes are executed within the authentication mode in IIS CAS servers. To do this open IIS and select the Default Site and click in Autentication. The example shown below this: Select the item Windows Authentication and select Advanced Settings, this way we can see how the item is configured within IIS. At this time we locate our error, because by default setup Windows Authentication, can not be setada in IIS, this type of configuration was adopted in Windows Server 2008 R2 as Extended Protection already at the beginning of article got a tip about the problem we are facing , below is a short summary of the article cited above in Extended Protection: Exchange Server 2010 Service Pack 1 (SP1) supports Extended Protection for Authentication. However, by default, Extended Protection for Authentication is not enabled on computers running Exchange 2010. Fix Error To solve the problem, just make the change within Advanced Settings, as shown in the figure below. After this procedure, restart IIS (iisreset / restart), so that the procedure works and the error does not occur again in the CAS Proxying scenario.
