Resource can't connect to server.
 

I have an Exchange Server which I previously configured for resources.
Meaning I was able to setup resources with an exchange mailbox in AD,
and configure them in outlook to autorespond to meeting requests.
Around the end end of 2006 our Exchange server got upgraded and
everything went smoothly, or so I thought. Since this feature was
never used and was still in testing mode before the upgrade, I didn't
find out until recently that it stopped working after the upgrade.
Usually when I try to setup a resource, I login the resource in
outlook and go to
Tools-Options-Calendar options- Resource Scheduling. Since the
upgrade when I do this, outlook hangs and comes up with the error
message, "The connection to the microsoft exchange server is
unavailable. Outlook must be online or connected to complete this
action."

I have tried deleting the users and recreating them. I've tried to
look for answers online for months, but so far I wasn't able to find a
clue as to what might be my issue. Can anybody please suggest
something? Thanks in advance.
