Activesync Not Working After Exchange 2007 to Exchange 2013 Migration

As I continue my journey into migrating to Exchange 2013, I've come across yet another morsel of knowledge to pass along.

In the process of testing my new Exchange server, I selflessly migrated my account over from Exchange 2007 to test that everything was functional.  Much to my dismay, my iPhone stopped receiving email.

I tried rebuilding the email account on the phone and checked every server setting that I could think of.  Everything was set correctly.... or so I had though.

Turns out that the migration to Exchange 2013 left a single Active Directory option unchecked that prevented certain permissions from propagating.  And surprisingly enough, this phenomenon only affected users with Domain Administrator level security.

So here is how I resolved it:

1. Pop open your Active Directory Users and Computers console and ensure that you have the Advanced Features option checked.



Turn on Advanced Features

2. Next, navigate to your affected user and open up Properties, then click the Security tab and select Advanced.



In the Properties of the affected User, under Security, click Advanced

3. In Advanced Security Settings for the user, under Permissions, check the box that says Include inheritable permissions from this object's parent

Check Include inheritable permission from this object's parent

And that's it.  After that, ActiveSync will kick back on for your Admin user.
