I have an Exchange 2003 box that is read by an old POP3 application that has no configurable options apart from server/username/password, and it's deleting the old messages from the mailbox after it has finished.
Is it possible to force Exchange to not delete the messages? I'm guessing there's some permissions I can set somewhere but I hate Exchange 2003 and I've no idea where to even start looking.
I've got every intention of moving it to Exchange 2007/2010 in the future, so if anyone knows any solutions for 2007/2010 I would be glad to hear them as well.
