Hi we are testing Office 2016 and have noticed that Autodiscovery in Outlook 2016 works a bit different than in Outlook 2013.
In Outllook 2013 Users where not prompted to give their user password when starting outlook for the first time and using autodiscovery.
When starting Outlook 2016 autodiscovery works and finds the needed information about the users but the user needs to provide user password. Is this because OAuth is only supported with Exchange 2016?
