On top of what Russ said, this message specifically indicates that your PST
is read-only. Either it is on a CD or you have copied it to hard drive but
have not removed the read-only attribute.

What is the best way to transfer all the data from 2003 to 2007 or
does anybody tell me why this is happening?
