I have a folder which contains all messages to a group of contacts. After they are 30 days old I want to move them to individual subfolders, one for each addressee but because the email may have been sent to several people in the group I need to Copy rather than Move. Is there some way I can prevent an email being copied if it already exists in the target folder? I know I can manually remove the duplicates from a folder with Delete Duplicates but it would be nicer not to copy them to start with. I delete the emails in the source folder after 60 days at the moment but would be quite happy to delete it immediately after copying if I could be sure it had been copied into each relevant subfolder. Anyone got any ideas?
