I am currently having trouble with the last stage of configuring Exchange/Outlook in our organisation.
We are having issues with an SSL Warning when opening Outlook 2013, where it is failing to validate the SSL, as it is using our (old) Internal URL (exchange.internal.local).
Please see the config within Exchange below, however I'm not sure what is causing this, if it helps it doesn't seem to be happening in Outlook 2007

!!EDIT!!Also if it helps, running the Exchange through Test Exchange Connectivity reveals the following:
