Exchange 2013 Autodiscover Android IOS not working

Hello,

I configured exchange 2013 in my organization. Android, thunderbird and IOS not working with autodiscover.

Windows Phone example Lumia worked with autodiscover correctly.

All needed DNS entry and certificate are uploaded to Exchange.

Test on https://testconnectivity.microsoft.com/  ended successfuly.

Can Android and IOS supported autodiscover.
