setup another exchange 2013, COMODO 3 month free cert and activesync error

- I get COMODO 3 month free cert for testing purpose, I can install it, but the exchange 2013 regard it as invalid. there are some dicussion on the net regarding this essential cert. namely COMODO suggests using the UC cert.

- another issue is active sync not working properly for an administrator user ( haven't got other user to test)
it's a permission issue I encountered years ago

1. Open Active Directory Users and Computers.
2. On the menu at the top of the console, click View > Advanced Features.
3. Locate and right-click the mailbox account in the console, and then click Properties.
4. Click the Security tab.
5. Click Advanced.
6. Make sure that the check box for "Include inheritable permissions from this object's parent" is selected.
