Domain has been totally changed with same client

Hello experts,

We had a Windows 2008R2 DC with Exchange 2010 on the same machine being used for semi-testing purpose only.

The only domain controller and exchange server was degraded and a new Server 2012 DC with Exchange 2013 were setup using the same domain name testlab.com

Few computers have been joint to the new domain successfully and they are using outlook with Exchange very well.

The problem is in a Windows 8 basic version computer which is not a domain member, but unable to setup Exchange account on it. It gives the below error message always. I have tried lot of work arounds like opening a new mail profile, using a new Windows user profile, and didn't succeed.

"Cannot start microsoft outlook, cannot open outlook window. The set of folders cannot be opened.  You must connect to microsoft exchange with the current profile before you can synchronize your folders with your Outlook data file ost.

I have tried creating a new local user account on this computer and tried using the same for testing this but didn't succeed also.

Any help?

When a computer is not a domain machine it requires autodiscover to get the services it needs to connect you to your mailbox. If you cannot access autodiscover from this machine you will not be able to access you mail through Outlook. Do you have the correct DNS settings for this non domain machine?

Also, you are going to want to setup Outlook Anywhere for your Outlook client to properly connect without being on the domain. You can also use OWA as well, but as stated you need to have the DNS servers from the domain in your Win8 client NIC settings.
