Exchange 2010 - LAN users being prompted for username/password
Got an issue with a fresh Exchange 2010 install. One Exchange server with all roles installed.
When users open up their Outlook client (Outlook 2007), they are continually prompted for their username/password. Further more... it will not accept their correct credentials, and you have no choice other then to hit cancel a few times and then Outlook works as usual. They will continue to get prompted sporadically throughout the day.
We have correctly configured Autodiscover and installed a valid SAN cert with all the correct names. OWA, activesync and Outlook Anywhere (for users outside the office) all work fine. This only effects local LAN users on the Domain.
At a loss, I opened a Microsoft support case and have been working with them for 4 days now... and they themselves are currently stumped.
After a week of troubleshooting; here's what we know....
1) Any user running a Outlook 2010 client, do not get prompted and work fine.
2) Any member of the "Domain Admins" group do not get prompted and work fine.
The above are obviously not valid solutions....but a "work around" so to speak found solely through troubleshooting.
I am posting this question here, if not for anything else, for chronicling purposes to look back on when this issue inevitably raises its head for another client and to help out all those who I know are experiencing this same issue as well.
If you have any comments or suggestions that may aid in resolving this ... I'd love to hear them!

Had a similar issue last month with Outlook 2007 clients. Don't know about 2010.
Microsoft had issued a KB2412171 last month that made Outlook 2007 users get a logon prompt repeatedly. Simply uninstall the KB2412171.

Sunny - The first thing we did was run the ExBPA. Test clean...no errors at all...
Regarding the www.testexchangeconnectivity.com site... the only test out of all of them that failed was the "Synchronization, Notification, Availability, and Automatic Replies (OOF) " test.

ASKER
All users having this issue (prompting for credentials), are local LAN users. VPN or any other user OUTSIDE the office works flawlessy via Outlook Anywhere.
ASKER
And yes... the users are logged into the domain when opening outlook.
That's strange :)

If it still doesnt fix the problem, can you enable Kernel Authentication mode as per this article by demazter
http://demazter.wordpress.com/2010/02/09/outlook-continually-prompting-for-username-and-password-2/

I will try that Sunny... thanks.
Yea, we originally had Kernal Authentication enabled... but Microsoft recommended we turn it off for some reason. Either way, made no difference...

As a follow up Sunny... I did restart the serivces and even rebooted the Exchange server. No change unfortunately...

Special thanks to Sunny for all your help and ideas. This was truly an odd issue and I hope this resolution from Microsoft can help others.
FYI - performing this solution and then doing an iisreset caused all Exchange clients to disconnect (yikes!). Restarting the server caused everything to come back up and the authentication pop-up issue window to resolve. Thank you much to Italia_NYC for going through the pain to resolve this horrific issue!
Thanks for coming back and updating the case.
a) Check if Exchange autodiscover Internal URL's are configured appropriately to local exchange server / CAS Array
b) Check if there is a certificate mismatch.
Tests:
a) ExBPA
Download and run this
