Active sync not working on Exchange 2013 Server

Hi

I currently migrating my current users from Exchange 2010 to Exchange 2013 ,in the migration I still need my users to connect their phones/devices with ActiveSync on Exchange 2013 Server. The OWA address works like a charm on Exchange 2013 but can't get my users to connect with the public ip of the new Exchange 2013 Server ,Please advice what I can do

Thanks

Run activesync manual test and inform us about the error. Based on the error anyone can suggest the troubleshooting steps.

-Check if it is not working for single user or all users.
-Check in  inherited permission are enabled for the users.
- is your AD domain and smtp domain same? i.e is your internal domain abc.com and smtp domain abc.com or abc.local and xyz.com. If your internal domain abc.com and external domain xyz.com then you will have to add addtioinal upn suffix in AD for xyz.com and set primary upn for all the users to xyz.com. this wont affect domain login but will be helpful in accessing activesync using autodiscover.

Your external host name seems to be owa.abc.co.za whereas your certificate seems to have owa-Exchange.abc.com.

If you are already using a valid thrid party certificate then check what is the name you have in your third party certificate and change the Exchange url's accordingly.
If you do not have a valid third party certificate then purchase a valid third party certificate according to the url's you need.
