We have existing Exchange 2007 SP3, and we just installed 2 Exchange 2013 SP1 in DAG configuration to co-exist with Exchange 2007. Everything went smoothly with the installation and configuration.
The OWA is working perfectly fine BUT our problem is with the Outlook anywhere, All new users(Outlook 2010,outlook 2013) cannot connect to the new Exchange server 2013. The Error is The action cannot be completed. The connection to Microsoft Exchange is unavailable.Outlook must be online to complete this action. The exchange 2007 clients are still ok connected to exchange 2007.
Below is the details with Outlook anywhere and the Autodiscovery for your reference.
