2. Receiving error message “the target princible name is incorrct” when trynig to access exchange web access after publishing from ISA

3. Unable to authenticate user when open outlook web access

4. Certificate error on the client machine when accessing the outlook web access

Solutions were Applied on the Problems:

1. Unable to receive internet emails: No receive connector was active on the exchange server, new receive conectior added and activated on the server

2. Receiving error message “the target princible name is incorrct” when trynig to access exchange web access after publishing from ISA: This was a certificate problem, the client was trying to access the page with an address was not the same as the internal address used on the exchange server, two certificates were added and used on ISA server and Exchange server, the first certificate was the public name for the web access, and the other one was for the internal name to use it between the ISA and the exchange servers internally, these two certificates were also exported to ISA server and we used the public name certificate on the SSL listener in the publishing rule..

1. Unable to authenticate user when open outlook web access: this was a problem in the authentication method of the publish rule of the exchange outlook web access, the rule using the HTML forms authentication with the domain name defined, the domain name was defined wrong so the client was only able to authenticate if he typed the user name with this format: username@domainname, fixed the domian name and the authentication is working fine

2. Certificate error on the client machine when accessing the outlook web access: just installed the certificate from the web page to the personal store and the client is trusted the server and the certificate error message is no longer appearing when openning the outlook web access page
