Active Sync error with Exchange 2010 Sp1 "Failed to create the account. Please try again later".

ExI have seen this error many times with iPhones, etc. This has been easily fixed every time by simply doing the following.

You will need to have access to Active Directory.
1. Go Active Directory Users & Computers (Enable Advanced Features if needed)
2. Open the properties of the user that is having the issue
3. Click on the Security Tab
4.Click the Advanced button
5. In the Default Permissions tab check the box at the bottom for "Include inheritable permissions from this object’s parent"
6. Wait for AD to propagate
