I am installing Home and Business 2011 on a MacBook Air (10.6.8). The machine has Entourage 2008 on it and is connect to Exchange 2003 Server. I want to install Office 2011 and not use any of the Entourage data. In fact I will point it to Exchange online. However after I have installed Office 365, I get the error "Could not change to that identity. An unknown error has occurred in Outlook.

I have tried pressing alt and opening outlook and rebuilding the database however it will not go pass step 1.

I have managed to get this work in another Mac however this one and another get the error. The version of Office 2011 is 14.2.2 right out of  the box.

Thanks

Barry
