Thank you very much, I also configured redirection and only then noticed problems with my OAB. This fixed the issue.

Thanks again.

Good post!

I had to go a bit further with my exact same problem. Turned out to be a group policy object which turned off BITS bandwidth during working hours, so that WSUS updates would be applied after hours.

Tom, thanks for posting this; I configured OWA redirection for a client 2 weeks ago and wouldn't have even connected the dots when running into the issue just today.

FYI only 'Read' permissions are required on the Web.config file, not Read & Execute.

Had the same thing happen in Exchange 2010. 3 hours on the phone with support and this was the fix. Thanks!

Hey all – I know lots of folks still have OAB issues. I found a STRANGE resolution for my own personal w7 outlook 2007 sp2 client. I, the exchadmin, was unable to download the OAB. After much head-bashing I was shocked to learn that Exchange/Outlook use BITS to transfer the OAB. I had a throttled BITS job that appear to be stuck. Run “bitsadmin /list” from the problematic workstation. If you see ‘Microsoft Outlook Offline Address Book’ listed a bunch of times as QUEUED but a differing job “TRANSFERRING” try canceling the job that’s “TRANSFERRING” by running “bitsadmin /cancel” and paste the {whatever} job name after /cancel that you found from /list. Include the {} brackets. Worked like a champ here. wipes brow

Thanks… it worked for me. some selected the redirect for owa and the web.config file lost its permisions. reset access permissions on the file and restarted iis. Its all good.

Jason, RU8 should actually disable the kernel mode authentication for you now.

Do you get an error in Outlook when you try to download the OAB?

I’ve completed the settings listed above, but outlook still doesn’t seem to be able to download the offline address book. I have Exchange 2007 SP1 Rollup 8 installed on a W2K8 server. Any other suggestions would be GREAT.

Thanks in advance, Jason
