How do local Microsoft Office applications (Word, Excel, etc) authenticate with Office 365? If I open, say, Excel or Word, then my name and email address automatically appears in the top-right hand corner and I create local/cloud documents from the get-go. However, if I open Outlook or Lync, I have to authenticate. Does anybody know what's happening here?
For background: I've set-up a trial Office 365 account to play around with the functionality and learn what it does. So far, I have configured my Windows domain, set-up a bunch of users, configured DirSync, configured password sync, configured Federation Services and everything works great. I log on to my domain computer, open the browser, hit
http://login.microsoftonline.com/, enter in my federated user, it redirects me to the ADFS server and I'm in. Happy days - no passwords.
However, I'm not sure where I stand with local apps. I would, where possible, like to authenticate using ADFS and avoid entering username/passwords. Could somebody elaborate on what my options are?
