Hello All
I got it done....in my case it was a server setting to be done by the exchange admin..there is a inherit permission to set on active directory...it may take 30 mnts (or as per ur server settings) to replicate the setting and then it will work...
You're exactly correct.
1. Go to a Domain Controller in your domain
2. Open ADUC (Active Directory Users and Computers)
3. Navigate to the user in question and right click
4. Click Properties
5. Select the Security Tab
6. Click the Advanced Button
7. Check the "Inheritable permissions from this object's parent" checkbox
8. Click OK
9. Click OK
10. Close ADUC.
It seems that there was a permission problem with active sync, AD and Exchange 2010. From my research, users created prior to an Exchange 2010 (upgrade from 2007 in my case) didn't have the right permissions on the user to allow active sync. Checking that box makes sure the permissions are correct when using default permissions on your servers. I'm not sure what permission is being added as I haven't delved that deep into the problem, yet. If your Admin has unique security settings for your domain this may not work. You may have to figure out what permission is missing from the user and add it manually. So far this has fixed about 10 of my users who have the exact same problem as everyone here. I'd say it's probably a good idea to try all the fixes listed in this post first before you bother your administrator. After that, show him this post and he'll know what I'm talking about.
