Exchange 2010 server Outlook 2007 and 2010

bmeltzer2 used Ask the Experts™
For some reason in outlook the GAL (Global Address Book) is not updating. And when. in Outlook you click to download the GAL\Offline address book it just sits there forever - I a have waiting over 8 hours and there is no progress. It seems as if the client is not connecting to the exchange server to get the OAB.

I ran Fiddler and saw that several client (Domain Users and Domain Admin) can tunnel to without issue.  But they cannot tunnel to the FQDN of the Server name which it seems to want to do when downloading the OAB.

How can I resolve this?

Do you have Exchange 2010?

do the following:
1- go to the Exchange management console, check the mailbox database properties, and on the client settings tab check to see if the OAB is selected.
2- remove the cached mode from outlook and see if the OAB is downloaded.
3- test the use of out of office trhrough outlook. the reason being is that OOF also uses autodiscover. and that's a quick way of seeing of your autodiscover service is ok.

post the results.
Whenever you suspect an issue with the GAL always connect to the mailbox using OWA to verify new objects are present

it sounds as if you have an issue with your OAB
first use the Exchange Management Console to verify that your OAB is published using web folders, if not is will be trying to contact a public folder

then you can run the test e-mail autoconfiguration tool to retrieve you OAB URL
attempt to browse to that URL (add a /oab.xml to the end of the URL)
make sure you don't get any certificate errors when browsing, if you do you need to update your certificate with either a third party cert or install the current certificate locally to trust it
