This is one we get on the helpdesk a lot, how do I reprint my remittance? Well if you have fully posted the payment the simple answer is you can't. however with the new email functionality in Dynamics GP 2010 you can, with a small work around.
Simply set the BCC email adress to a generic mail box that everyone in finance has access to. This way when ever a remittance advice is emailed out it will also go to this addresses inbox. then if you need to re print it you simply go to the generic inbox and forward or print. This gets round the issue of the sent items being in indervidual outlook accounts for each staff member.
