OWA Not working on new install - 21.Dec.2008 4:58:56 PM

Hi,

Brand new install of exchange 2007 running on windows 2003 x64. Owa will work all ok internally but not externally. I get the main screen to log on and then fails on https://mail.domain.co.uk/owa/auth/owaauth.dll just keep getting http 400 bad request. This is a new install and the only things I have changed are opening ports 443 and 25 inbound. Also altered owa external address to be https://mail.domain.co.uk/owa. The domain name internally is different so is internal.local. Really cannot see what is the matter with this ?

Any ideas appreciated.

Lewis,

Are there any events logged in you event logs ?
Also check this article:

http://technet.microsoft.com/en-us/library/dd159912.aspx

Although it doesn't look like this is the issue because internally it works. Did you also try to test it via Powershell:

Test-OwaConnectivity �URL https://mail.domain.com/owa -MailboxCredential (Get-Credential domain\username)

John,

Regarding technet this is iis7 ?

Also with the script I got

WARNING: The test was unable to log on to Outlook Web Access because the SSL
certificate did not validate. You can force the cmdlet to proceed by re-running
it and specifying the ?TrustAnySSLCertificate parameter.

Any Ideas,

Thanks,

Hi,

This is logical because the parameter will ensure that the certificate is not checked.
So the issue is caused by the certificate. Do you use a self-signed certificate ?
If so then buy a commercial certificate.

Hi John,

Yes it is a self cert but the issue is that a customer has this setup and I am wondering how it works ?? I did not install this setup.

I know about the commercial certs and the benefits and totally agree but how did they get this working. I am trying to replicate what they have ???

Thx

Hi,

OK and has the customer also got a self-signed certificate running on it ? I found some issues where the certificate is the issue and reinstalling it fixed the issue.

yes it is due for the 1 year soon hence looking at this. Is this an issue where the internal and external domains are different. For speed I was going to renew the self cert and then look at getting a comercial cert later. For renewing the cert can you send me any links......

Thx

My first question would be is the mail server offering the bad request or Internet explorer?
Secondly, is World wide web publishing services started?

And third, in IIS under the properties of the Default website.. do you have IP's "All assigned"?

That is what it should be in most cases.

If he is getting the bad request, wouldn't that indicate he is not even at the certificate level yet? Not sure, but just a thought.

If the exchange server is providing the error, you'll see it referenced in the error in most cases. try the OMA at the end of the URL less the OWA

This error (HTTP 400 Bad Request) means that Internet Explorer was able to connect to the web server, but the webpage could not be found because of a problem with the address.
For more information about HTTP errors, see Help.

OMA gives page cannot be found

Thanks,

are you going to https://yourdomain.com/owa or http ? Not sure where you were with the certificate.

I would almost bet at this point it is an issue with the Setup in the IIS.

Oh check this out... Interesting

No problem... Also if you are not using IE7, upgrade because there are reports that this is fixing this issue
