My email has been working fine, but sometime yesterday, Outlook started acting funny. I wasn't receiving any email at all, or at least it looked that way. For some reason, one of my rules started routing all of my new mail into a folder, even email that wasn't addressed to match the rule. I disabled that rule and now my email comes to my inbox. But now when it does a send/receive, it sends fine, but hangs up when the receive tries to download the OAB. The send/receive details show that it's working on "Offline address book Connecting to Microsoft Exchange". I've tried turning cache mode off and back on. I've rebooted, I've restarted Outlook. I downloaded the OABInteg.exe util amd ran /alltests and get this error:
OABInteg (Offline Address Book Integrity Checker)

LDAP_SERVER_DOWN - ERROR_DS_SERVER_DOWN: Cannot contact the LDAP server...
Failure in function: HrGetRootDSEData on line number: 165
We have two domain controllers at this location and a dozen more at various other locations on the VPN. So I have no idea why it can't contact the LDAP server. There is no log file written at c:\OABinteg.txt. Nothing else is complaining.
If I ctrl + right click on the Outlook icon in the tray and choose 'Test email Auto-Configuration', all the results come back successful. If I do the same thing and choose connection status, it displays two connections to one of our domain controllers and the exchange server, with no failures.
I've looked at everything I can think of but am stumped. Can someone point me in the right direction of something else I can check?
