I have a recently deployed Exchange 2010 server, currently co-existing with a Exchange 2003 server that will soon be decommissioned. All mailboxes have been migrated to 2010, as have replicas of all Public Folders. Problem is, I have a few misc Outlook clients (2003-2010) that are not receiving updates to the Offline Address Book. For example, a Outlook 2010 client that I tested, doing a manual Send/Receive of OAB results in the progress stalling at "Processing." Knowing that for Outlook 2007-10 the OAB is downloaded from Exchange 2010's Default Website's OAB directory, I tried opening https://SERVERNAME/OAB
to which I received a 500.19 - Internal Server Error. (The requested page cannot be accessed because the related configuration data for the page is invalid.) I thought I found my answer when I came across this article: http://www.confusedamused.com/notebook/oab-never-downloads-for-outlook-2007-clients-with-exchange-2007-on-server-2008/
I had, in fact, setup redirection for my default website per TechNet: http://technet.microsoft.com/en-us/library/aa998359.aspx
and was careful to disable redirection for the OAB virtual directory. But when I followed the article's suggestion, and from Windows Explorer modified the Security Permissions for the web.config file in the C:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB folder to add Authenticated Users read and read and execute permissions, I still had the OAB issue, and my redirection stopped working for the entire default website. Per one of the comments on the ConfusedAmused article, I even tried adding the same permission to the NETWORK SERVICE account to the same results. I'd be grateful to any suggestions on how to resolve my issue.
Thanks in advance,
