title: Outlook 2013 issues with office 365 and onsite Exchange server
body: <p>Our Global company is in the process of rolling out office 365 for the whole group. currently i am the only user in my location to start using office 365. I can create a new outlook 2013 profile for the office 365 account and it works well. Problem i'm having is after launching the new Office 365 profile outlook keeps prompting me for my local windows username and password. this only happens when i'm connecting to my local network. Our local exchange server is still in production and cant be removed at this stage as all my other 400+ users use it. </p>
  
  <p>If i connect to my office 365 profile in outlook from another network this does not happen. </p>
  
  <p>I created a new profile for outlook 2013 and this still occurs. 
  If i enter my credentials in outlook 2013 it downloads my local OAB instead of using the new Office 365 address book. 
  Current setup: Local Exchange 2007 server.
  Office 2013 on windows 7 64bit </p>
