Its not entirely clear as to whether you are trying to open a data file or
merely copy from one to another

There is a free OL backup addin on MS OL site

Generally you copy a pst (data file) to some other location ONLY when OL is
closed - do it whilst OL is open and you will corrupt the data file

DL, reading from one of your responses dated 7.29.07 4.34 am quote "OL
FileOpenData File.....browse to location" when I highlight the file,
archive.pst right click copy and try to paste into a folder, it says
"cannot
copy archive..."

Likewise I also cannot paste the contacts.pst and there is a message '
cannot copy contacts.The process cannot access the file because another
process hasloaded a portion of the file".

So how can I transfer and back up the emails, thanks
