ActiveSync will not connect to Exchange on Phone/Tablet

If you are not able to connect to your Exchange email via a mobile phone/tablet (I've seen this on Android and Windows phone), then the following should allow connection

• Open the Active Directory Users and Computers and go to “View” and select “Advanced Features”

• Find the user who is not able to use the ActiveSync, and double-click him, and go to “Security” tab then click “Advanced"

• Then check the check-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 ActiveSync on the mobile device
