Hello, This is my first time posting, but I've run into a problem that's rather unique... My organization hosts a multi-language web application that uses cookies to keep track of session IDs. The way it works is that we use different URL schemes in order to determine the language we are serving content in. Here's an example: www.domainname.com - English deutsch.domainname.com - German espanol.domainname.com - Spanish Here's the problem... We recently set up Exchange 2010 and are loving it. However, we're running into a problem were we set OWA access to 'webmail.domainname.com'. Now, if a user logs into OWA first, a 'sessionID' cookie gets set for OWA and all is good. However, the second the user browses to our website, the 'sessionID' cookie gets clobbered by our WebApp as it needs to set the cookie for *.domainname.com. The next time the user browses to OWA, they are greeted with the login screen. It then becomes impossible to log in. Is there a way to ask OWA to rename their session cookie from 'sessionID' to ANYTHING else that would be unique? 'outlookSessionID' comes to mind, but ultimately it doesn't matter. Is this configurable anywhere in the OWA configuration files or registry? Thanks.

Hi Juan, I don't believe you can do this either via the web.config for owa or via any cmdlets. Have you tried switching from Forms-based authentication for OWA and ECP? If that's not suitable your best option may be to rename your cookie in your app. Steve Steve Goodman Check out my Blog for more Exchange info or find me on Twitter
