My setup: 1 - Exchange 2003 server SP2 - Hosted on a Win2K3 SP2 server DC running DNS and WINS. 1- Exchange 2007 server SP1 - Hosted on Win2K3 SP2 server running the HUB and MB roles 1 -Exchange 2007 server SP1 - Hosted on Win2K3 SP2 server running the CAS role. End Goal To have Exchange 2007 only. I don't care if I need to leave the CAS server separted. I did that as a recommendation because of OWA and public folders. The CURRENT issue. I'm trying to redirect http://mail.company.com to https://mail.company.com/owa after following this article --> http://technet.microsoft.com/en-us/library/aa998359(EXCHG.80).aspx I was able to successfully redirect http://mail.company.com to http://mail.company.com/owa but when I attempted the https portion I seemed to have taken a step backwards. Now when I try to go to http://mail.company.com I get this message " The website declined to show this webpage I have to type https://mail.comany.com to can then get logged in, but if I try to access a public folder resource, I get prompted to authenticate again but entering credetials doesn't work. It just pops up a NEW logon box. I would like to get to the point where all redirections work as expected and also allow seemless access to public folder resources. Any help would be greatly appreciated.

Hi, Regarding the public folder part you should compare the security settings on the /public directory with the security settings on the /owa directory on tbe CAS server. Leif

Hi, First Id like to know what URL that you used to logon OWA. As theres CAS in your Exchange organization, then I assume https://.../owa should be work when user on Exchange 2007 logon OWA 2007. So as my understanding, you want to direct the OWA 2003 URL to https://mail.company.com/owa,is that right?

I'm having a somewhat similiar issue, except the Public Folders. In my case, this a completely native Exchange 2007 envrionment. I created a redirect page and edited the custom errors as directed by the artciles linked above. This worked for some time, but has stopped working with the exact 403 error code reported by the thread starter. The only thing I can think of that I might have done to cause this is deactivating the old SSL certificate and issuing a new multi-domain certificate. Besides that I'm completely at a loss.

HiMadavid, Then you need tocheck whether the newly installed certificate has been issued to the right web site.Please note "issue to" should be the same as url that you want to access. Besides,if the issue is persisting,then I recommend you to startup a new thread ,we will focus your issue there. Thanks, Xiu
