For Outlook 2010 autodiscover was not required but for Outlook 2013 and 2016 it is.
If you see problems with 2013 and 2016 outlook versions  then probably your autodiscover is wrong configured or not exists.

Double check

it problem is in your local network you can simply fix that by creating2  New Forward Lookup Zones:

First one name it -  autodiscover.yourdoman.local (or com) depends on your local domain name
Inside just put your DNS (or two if you have more)
(same as parent folder)      Name Server(NS)      exchangename.yourlocaldomanname.local

Second one name it - exchangename.yourexternaldomain.com
(same as parent folder)      Name Server(NS)      exchangename.yourlocaldomanname.local
(same as parent folder)      Host(A)      192.168.1.10 - Your internal Exchange IP address

it should resolve your problem.

All of the settings do not have a problem in local network :-(
Ehab,,, Certificate is specially used for connections from outside, that's why I was asking you to check if your autodiscover is placed in your certificate
i'm useing Internal CA; and installed CA certificate in trusted root
 
DNS Name=mail.eh-abdallah.com
DNS Name=AutoDiscover.eh-abdallah.com
DNS Name=eh-abdallah.com
DNS Name=www.eh-abdallah.com
Your certificate is NOT VALID, that's why you have problem with outlook 2013 and 2016 from outside
