Outlook 2010 will not connect via TCP/IP but will with HTTP.

So I just built a new terminal server, Windows Server 2008R2sp1.  Outlook will resolve my Exchange CAS array within seconds, but won't actually fire up.  Says the server is unavailable.

HTTP(Outlook Anywhere) works fine.

All of my other clients seem fine, my other terminal server is fine.

I've re-installed Office multiple times, even rebuilt the server entirely(its a VM), same problem.

I'm obviously missing something here... the question is, what?

Do the two terminal servers have the same version of Windows and Outlook (updated to the same level)? and the IP settings are the same (i.e. both getting a reserved IP from the same DHCP server, or at least both with the same exact static settings other than their own ip of course)?

Well, the one server is quite a bit older, so updates probably were not installed in the same order, and some of the updates on the new server may have been a part of rollups.  

One other thing of note.. The new server uses 32-bit Office, not 64 like the older one.  I use 32-bit Office on servers that need to access SharePoint, or else Excel has issues.

I have yet another terminal server that only one department uses which runs 32 bit Office just fine though.  Just verified that, actually.

Any firewall in use ?
Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Firewall is off.

Office sp1 is installed.

No office on Exchange.

Yes, I've tried to create a new profile.  Many, many times.

I'm noticing that while this server can ping the CAS array, it can't actually resolve it in Outlook... odd.

Using an E1000 NIC instead of VMXnet solved the issue.  Not sure why.

I'm not sure why but the virtual NIC must've been having issues.
