1. What's your configuration as far as CAS:
a. OWA: Internal FQDN is the same like external one, authentication is integrated windows authentication and basic authentication
b. ECP: Like OWA
c. ActiveSync: Basic authentication, ignore client certificate
d. OAB: Internal like external
e. OAW: Basic authrntication
2. I cannot see any difference
3. 2007 and 2010
4. Windows authentication and basic authentication

I would add this question:
Is this new problem? Did it just start happening after days / months of working just fine?
If it is a new problem, then look for what was changed.
Also, is the problem consistent: prompted users are always prompted, others are never promtped?
Lastly, are all affected users domain members (or more accurately, are their computers Active Directory domain members)?

I've found this often has to do with the OAB. You can test by updating the mailbox with and without the address book.
Tools > Send\Receive > Options here for S\R

domingo, 29 de abril de 2012 9:44This is a problem that emerged suddenly, our exchange server deployment is new. For some users it keeps prompting. Users machines are all joined to the domain. Wjhen I try to download address book from send\receive, it stucks on offline address book connecting to microsoft exchange

There are some suggestions in this thread for an OAB that does not download:
Without repeating the whole thread, I'd ask what clients you have?
Just Outlook 2007 and 2010? If so, you can eliminate OAB distribution by Public Folder and eliminate that as a possible cause.
I'm surprised by the solution (a wireless mouse?) but he does provide a reference from MS.
Note that in the right sidebar, there are often other references to this apparently very common (and very annonying) problem.

Hi Ahmad,
Firstly are you using a self Signed Certificate.
Secondly (if you are) what is the expiry date of the certificate.
The reason why i ask this is because, in my experience 9 times out of 10 i find that the Self Signed Certificate has expired and requires replacing.
if so you can do this by using the following the steps outlined in the following link:
http://technet.microsoft.com/en-us/library/ee332322.aspx
after you have done this you may will also have to enable the certificate for SSL by using the following command:
enable-certificate -thumbprint <insertthumbprint> ssl

Hi,
I am using a private CA from my internal CA server

lunes, 30 de abril de 2012 6:48so what is the expiry date on the SSL certificates... (sorry to bang on about it, but like i said, this is a classic Expired SSL cert issue)

can you open OAB link by typing that into IE
-
lunes, 30 de abril de 2012 16:34It gives
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

did you browse to <a href="http://server.contoso.com/OAB//oab.xml">http://server.contoso.com/OAB/<GUID>/oab.xml or just OAB?
you can enable failed request tracing in IIS to help troubleshoot the 500 error.

I tried both links and it presented me with the same error mentioned above. How can I enable failed request tracing in IIS to help troubleshoot the 500 error?
Also I wonder if a a client machine loses its connectivity to the exchange server for some reason, i.e. wireless or lan issue, it is expected to get this user name and password prompt, am I right? However if I cancel the prompt and re-open outlook, it does not ask me for the credentials that's why I am thinking that I may have network instability issue in my LAN...
What do you think?

can you verify that %PROGRAMFILES%\Microsoft\Exchange\ClientAccess\OAB is not empty and has proper permissions

martes, 01 de mayo de 2012 5:26I verified it is not empty and it has the appropriate permissions per the link.

martes, 01 de mayo de 2012 5:52 I think I figured out what is happening, I suddenly lost my connectivity to the network for few seconds and outlook automatically prompted me with the username and password dialogue box. I cancelled the prompt and closed outlook, re-opened it and it did not ask me to enter the credentials. It seems there is an instability in our network.

miércoles, 09 de mayo de 2012 11:18Ahmad, I have the same problem, but I cannot fix the network issues (VPN with lame internet connection). Is there a way to tell Outlook to just reconnect to the server without the password dialog?
