Fixing the problem when users cannot connect to exchange server using ActiveSync to sync their data

I don’t know if you got into this problem or not yet, but you should :-D

I got this problem and it took me 1 day to fin out what is going on…

The problem is you configure ActiveSync on the Exchange server and you put the certificate on the server and on the firewall (TMG or ISA) then when somebody with Windows Mobile tries to connect using ActiveSync, he fails, and cannot get to the server, even if you check about the problem you will find everything on Exchange and ISA or TMG is clear and no dust on it!

Well, the problem maybe not in the Exchange or the firewall, there is a big chance that you can solve it from the Active Directory!

Just open the Active Directory Users and Computers and go to “View” and select “Advanced Features”

image After that, find the user who is not able to use the ActiveSync, and double-click him, and go to “Security” tab then click “Advanced”…

image Then just check the ckeck-box “Include inheritable permissions from this object’s parent” and click OK to close all the other windows…


After this, the user should be able to connect to the server using ActuveSync with no problems…
