I am hoping someone can point me in the right direction?
We have a multitentant platform with Exchange 2013 using Citrix Cloud Panel. Currently, our Autodiscover works with any and all devices across all platforms with any issues. Its fast and reliable.
This was until Outlook 2016 for Windows. With MS removing the manual config of accounts, we are left with frustrated clients as the Autodiscover does not complete. You might be lucky the one day and it works with in 5min, sometimes you have to do it a couple of times and then sometimes it can take over an hour to work. (that is if it does.) With Outlook 2016, you don't even ever get to the logon request. It just stays there trying to find account config.
You can then take the same account and load it onto an Iphone or Office 2013 with instant account configuration and logon.
We have tried most if not all of the "fixes"on the web including the Regedit settings, GPO's, hot fixes etc.
Can someone assist with pointing me in the right direction? Is there something different in the way 2016 requests the info?
Hope someone can help.
