lowdre -> How to initially set up OWA (3.Jan.2007 3:06:52 PM)

Can anyone point me in the direction of a good white paper explaining how to set up OWA?

I don't think you'll find anything, because OWA is an integral part of an Exchange server, and can't be added or removed.  Try going to http://yourserver/exchange , and see if it's working.

Well, that does work, but it doesn't work outside our firewall.  Can you tell me how to configure it to use it outside our firewall - say, when users are out of the office?

You will need to forward incoming port 80 traffic (or 443 if you want to get an SSL certificate, and use HTTPS) to your Exchange server.  You will have already done something similar for SMTP (port 25).

And then?



leederbyshire -> RE: How to initially set up OWA (8.Jan.2007 4:08:31 PM)

If you've forwarded the port, then it should be ready for external access.  Have you tried it yet?



lowdre -> RE: How to initially set up OWA (8.Jan.2007 4:18:16 PM)

But would the outside http:// address change?  What would it be then?



leederbyshire -> RE: How to initially set up OWA (8.Jan.2007 4:23:52 PM)

Well, if you know the public IP address of the server, you could use that:

http://xxx.xxx.xxx.xxx/exchange

Since it accepts your incoming mail, the server probably also has a public DNS name (for example: mail.yourdomain.com), and you could use that:

http://mail.yourdomain.com/exchange

Ok, I got the whole thing up and running.  My last question is this.  How do I get the OWA to take just the username when logging in instead of requiring the fully qualified domain name?

Right now, we have to log in as domain\username or username@domain.local. 

I'd like them to just be able to log in as their username...

Thanks for all your valuable help!

You have to go into Exchange System Manager, and under Servers/<servername>/Protocols/HTTP/Default HTTP Virtual Server look at the properties of the VDir named Exchange.  Look at the authentication properties, and make sure that it contains a \ , or your domain name.



lowdre -> RE: How to initially set up OWA (9.Jan.2007 3:08:49 PM)

It does have our Default Domain as our default domain.  Should it be anymore specific than that?  Is there another place I need to check settings?



leederbyshire -> RE: How to initially set up OWA (9.Jan.2007 3:15:52 PM)

That really should do it.  Are you using Forms-based Authentication, but have not applied the Exchange SP2 to the server?



lowdre -> RE: How to initially set up OWA (9.Jan.2007 3:44:04 PM)

We're not using forms based auth.



lowdre -> RE: How to initially set up OWA (9.Jan.2007 3:45:12 PM)

And my ESM is only service pack 1 and so is my MS Server 2003.



leederbyshire -> RE: How to initially set up OWA (9.Jan.2007 3:49:43 PM)

If you're not using FBA, then the SP level isn't causing the problem.  There was a problem with the pre-SP2 FBA logon form that meant you had to edit it, otherwise it always required the domain.

I would try putting a \ in that auth domain input box.  If it says yourdomain.com, try just yourdomain.  If it says just yourdomain, try yourdomain.com .  You need to wait a few minutes each time you change it so that the new value can be copied from ESM to IIS Manager.



lowdre -> RE: How to initially set up OWA (9.Jan.2007 4:05:57 PM)

Neither of these options worked. 

What's weird is that it defaults to "roam.ourdomain.com\username" when you attempt to put the username with password in.  Making changes to the Virtual Default website doesn't seem to change this at all.

Thanks.

Also, this is only a problem with Internet Explorer.  Not Firefox.  ?? 



leederbyshire -> RE: How to initially set up OWA (9.Jan.2007 10:16:10 PM)

If you have Integrated Auth enabled (which is the default setting), then IE will try to use it.  Integrated Auth always requires the domain.  Firefox (being a non-MS browser) can't handle Integrated Auth, so will use Basic, for which you have set the default auth domain.  To make IE use Basic Auth, you will need to disable Integrated Auth on the Exchange VDir in Exchange System Manager.  The problem with Basic, though, is that your passwords are less secure in transmission.  To be really secure Basic Auth should be used with SSL, so that the entire session is encrypted.

Excellent!  We got FBA up and running.  My very last question (I swear!) is how do I force the http://site to forward to the https://site, forcing my users to use the secured site? 



leederbyshire -> RE: How to initially set up OWA (11.Jan.2007 11:03:44 AM)

There is an MS doc for this:
