  • 1. Exchange 2010 Single Sign-On
    I have looked and looked on google but I cannot find a solution to what I'm trying to do. I'm trying to get Single Sign-On working with Exchange 2010 OWA from our LAN. We are currently running a co-existance environment with Exchange 2003. All that's left to do is really just remove the exchange 2003 server from the environment. All the mailboxes have been moved to 2010. The way things used to work was you could just point your browser at https://exchange/exchange and it would automatically sign you into your email based on who you were signed into the computer. With Exchange 2010, it just keeps prompting for a username and password. I've tried both forms based and non-forms based (Basic / Integrated) but no dice. Any idea how I can do this?
  • 2. The name of the security certificate is invalid or does not match the name of the site
    Hi Team, We have recently moved from Exch. 2003 to Exch 2010 running Win 2008 R2. We have a SSL cert for the IIS (web mail) from Comodo and as a result we don't get any error's while accessing our web mail ( Whereas, the tricks comes to the internal outlook users who are connected to the Exchange through the FQDN. When they open the Outlook, they get the Security Alert pop window with the error message mentioned on the subject line. I created a self signed cert which contains the FQDN of the server and still in vain. Please provide me a solution. Thanks
  • 3. Distribution group with external contacts
    Hi, I have an issue with Exchange 2007. I have an existing distribution group which had internal accounts and worked fine. I have created a few contacts with external addresses. When I try to add the contacts to the group it can't find them, so instead I went back into each contact and made it a member of the group that way. When I send to the distribution group i get a message back which says "The recipient's e-mail address was not found in the recipient's e- mail system. Microsoft Exchange will not try to redeliver this message for you. Please check the e-mail address and try resending this message, or provide the following diagnostic text to your system administrator." Also, If I use OWA to write an email to the group. If I select the group for the "to:" field I can then click on each of the group members and a window pops up with their info. The internal ones show: Alias, email, organisation...all preseent and correct. The external contacts show the 'Organization' header but no information? What am I doing wrong? Thanks for any help, Dave

Hey all,
  This is driving me crazy.  I just want to have OWA use 
http(s)://  I have created a DNS record for the address 
pointing to the IP of my Exchange box and now it just won't connect without 
an error.  Basically, it asks for credentials (no forms based auth enabled 
yet) and then just errors after a while.  Is there a best practice for 
getting this to work?  I haven't done this in a really long time so I'm sure 
I'm just forgetting something.  Seems to me I had to change the default home 
directory of something on the Exchange box.  I can still connect to 
http://serverIP/exchange without issue.
This is obviously Exchange 2003 , sorry for not mentioning.

Try adding "/exchange" to the URL.

I think you're still at the IIS level right now. What's the full error
code (not just the three character 4xx, but the 4xx.n)?

If you changed the server name and you're trying to use HTTPS then the
name on the certificate isn't going to match the new name. You'll need
a new certificate.

Hey Rich,
  No SSL involved yet but that's next and I can handle that part 
(hopefully).  The current setup basically just routes to the "under 
construction" page.  I tried setting the home directory of the default 
website to be the same as the 'exchange' virtual directory and that failed as 
well (credentials box just keeps popping up over and over despite the correct 
credentials).  Using the  http://www.**--****.com/ 
result.  Again, I can still get things to work by putting in 
http://hostname/exchange or  http://www.**--****.com/ 
What am I missing?
Something tells me I have simple DNS issue.

If you think that's the problem then why not slap a line in to the
c:\windows\system32\drivers\efc\hosts file on the client?

This oughta do it:

Of course, isn't going to work. :-)
