History. Old profile got corrupted, created a new profile, transferred data etc across.

Couple of questions..

1. Was using Win 10 Mail app in old profile, and using it in new. Was setup with pop3 mail, need to get these emails across. Can't find anything online or in the program itself.

2. I can't see any setting in Win 10 Mail to set how long pop3 email stays on the server. Where can I adjust this?
