That is exactly what i have in my situation Nithyanandham

i check the permission in organization i will check the database permission

Thanks

I had the same issue in 2010.  We are running 2010 and a domain admin has only Manage Full Access to another mailbox but has the ability to "send-as" as well.  If you look in AD, Domain Admins have "send-as" applied even though it doesn't show up in the exchange "send-as" window. 

I was trying to figure out how this domain admin was sending as the other mailbox when he didn't have the "send-as" granted in the exchange console.  Found the permission applied to Domain Admins in AD.

Now without the "manage full access" granted, they can't send as.  In 2010 domain admins still need "manage full access" to another mailbox before they can send as.  At least that is what my testing showed.

inheritance will be denied for any protected ad groups.  if you set it to allow inheritance, it will revert back in 1 or 2 hours by itself.
