At my company they have there meeting room configured as a Resource in exchange so you can book it out at the same time of sending out the meeting requests. until recently this worked ok. However now when some tried to accept the meeting request they get the following system undeliverable message

I am assuming the issue is a permissions problem however I have given the everyone group full mailbox permissions to see if it is actualy a permissions issue but i still get the same issue.
Our current environment is Outlook 2007 / 2010 and Exchange 2003.
