We have a server running Exchange 2003. We've had problems with Apple products not being able to connect to the server (specifically Mac computers whether running Mac Mail or Outlook 2011.) We're planning on migrating to Exchange 2013 in the very near future. From what we've read many people are saying they are successfully using 2013, while others recommend sticking to 2010.
Our key question is whether Exchange 2013 will allow connectivity from an iPhone, iPad and Outlook 2011. We need all three or we will be forced to use Exchange 2010.
Has any expert tested all three?
