- Go into the user's account in AD and go to the Security tab.
- Check the box to Inherit permissions. If it's already set, clear it, force an AD update, and then check the box again.
I had 2 boxes do this on my last Exchange migration. It's a real pain to find out after you've waited on the mailbox to copy but a very easy fix.
