OK here's the scenario. We have an ISA 2004 server and an exchange 2003 server and I just installed an Exchange 2007 server. I've copied only one mailbox across to the exchange 2007 just to test and internally exchange 2007 works fine. But the very day I installed the Exchange 2007 sever We are not able to access the network exchange 2003 server anymore from home. When I tried to go to our school website which is www.athensisd.net the site loads. But the email link just basically times out that link is http://mail.athensisd.net. The interesting thing is if i enter https://mail.athensisd.net it pops up a warning saying the certificate I'm about to receive is invalid but that is the way its always been. After clicking yes the following message appears Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) Basically Why can't I or my users access the Old Exchange 2003 server at mail.athensisd.net ? Thanks for all the helps this is kind of a crisis.
