I switched back to tbird after an unhappy stint with a different email client. My web host (host gator) helped set up things so emails do not load onto my PC. I understand this means the "local" files and directory are not in use and that's great. I have two email accounts with the same name. Neither will let me change the account settings manually. Says "account with that name already exists." Can I safely delete the one that shows up on the top?
