Environment is two Servers running 2012r2.   server1 is acting a PDC running dhcp\dns.  Server2 is running Exchange 2013.  I can connect to exchange via owa but am unable to connect via outlook.      I can get outlook to authenticate the account but when I go to open profile I get error message that states .ost folders could not be opened. Outlook doesn't open if cache mode is not enabled.  Any thoughts?

Sounds like a DNS problem - Try using the actual IP instead of the Exchange Server name. If that works then adding a line in the client HOSTS file should work.  Have you checked the Domain controller's DNS settings to see if the Exhange server is pointed to the correct IP address?

What version of Outlook are you using? Is it setting up via autodiscover or are you manually having to add all server details in?

You can also check connection details on Outlook by holding CTRL and right-clicking on the Outlook icon in the taskbar notification area - you then have connection status or Test Email Autoconfiguration which can be used to check connections.

Regarding dns issues - try an nslookup from the client systems and the server - ensure it can resolve the exchange server hostname to the correct IP and vice versa.

I am running outlook 2013 and I am able to connect when manually entering the server name.  .

When I run nslookup on exch
I receive the following
unkown server  - This is PDC
192.168.0.3

exch.server.lan
192.168.0.2

when I run nslookup on pDC
Unknown server
192.168.0.3

server.server.lan
192.168.0.3

If you do an nslookup on 192.168.0.2 I assume it comes up with exch.server.lan and this is the name of your exchange server?

Looks like the DNS is getting confused with which ip is on exchange and which is on the PDC

Try your initial hookup to exchange server using the real IP

Sounds like you've got some dns issues on your DC/network. I would start by checking dns records on there and ensuring those are correct. Also check dns settings in dhcp and on the server lan connections to ensure these are correct.

I have been spending time in DNS and DHCP and everything looks correct.  I am still reviewing dns now.     DHCP is correct.

At the workstation - Admin level CMD  ipconfig /flushdns

Then do an NSlookup to the Exch Server
