Outlook Offline Address Book Error (Exchange 2010)

MasterComputing used Ask the Experts™
I have one user in my organization that keeps getting these messages in his sync log:

11:06:47 Synchronizer Version 12.0.6606
11:06:47 Synchronizing Mailbox '<name>'
11:06:47 Synchronizing Hierarchy
11:06:47 Done

11:06:48 Microsoft Exchange offline address book

11:06:48                Not downloading Offline address book files.  A server (URL) could not be located.
11:06:48                0X80004005

Everything looks kosher on the server, and I have tried disabling download of the OAB on this user's Outlook, but they continue to get this message about twice an hour.  Does anyone have any suggestions as to what the problem could be?  Thanks!

Here is something i found online


I found multiple websites refering to setting up the auto discover service
Raymond PengSystems Engineer

If it's only for one user:

I'd check for latest office / windows service packs and updates first.


Computer appears to be fully up to date.  I will try the autodiscover suggestion.  It is worth noting, however, that this computer, unlike the rest on the network set up with Outlook, is not joined to the domain.  Could that make any difference?


I created an A record for autodiscover, but it did not help.  Any additional suggestions?

Ok lets start chasing autodiscover. because thats were the problem is. do the following:

1- test activating out of office on that computer. it works? (via outlook)
2- test browsing to the autodiscover directory on that computer IE. should be https://autodiscover.domain.com/autodiscover/autodiscover.xml but to be sure use the exchange management shell command get-autodiscovervirtualdirectory |fl and see what are the externalurl and internalurl
3- is there a difference between that computer and the other in regards to proxy configuration on the IE? Try to remove the proxy from IE (if it has one) and restart outlook and try

post the results.
