I recently did a move from an old drive to a new drive on an Exchange 2010 Public Folder database. I also renamed the database from the default (Public Folder Database xxxxxxxxx). Now the event log is full of issues with permissions issues. It appears either the permissions broke or they changed when I moved the database. Any thoughts?

I don't think this (change files location)will cause permission issue. Could you post the events to let me know more detail about your issue? Thanks, EvanEvan Liu TechNet Community Support
