I am having weird problems in a new environment I just arrived at- Exchange 2007 SP2- 2 CAS/HT servers in a CAS array w/ NLB 1 MB Server Windows 2008 Servers, Domain, Functional Level OAB will not download at all on the Outlook 2007 clients. No errors on the client, or servers, even when diagnostic mode is set to export for MSExchangeSA | OALGenerator. It just times out when I manually download the address book, or Test Email connectivity. I have verified its setup correctly as far as IIS, its permissions and virtual directory. The \\exchangeserver\oab and the https://cas/oab directory contents look good, so I am not sure how to fix, since I don't know what exactly is broken. Any suggestions are VERY welcome.
