I know you're wondering why did I post this in the MacBook Pro section, well this is what my client is using along with an iMac and iPhone 4S. My problem: Client has a yahoo biz mail account (looks like: email@example.com) instead of it saying firstname.lastname@example.org. It's a POP3 account (might answer the question) We installed the account on the iPhone 4S, MacBook Pro and iMac. However none of the e-mails sync up together. i.e. if I delete an e-mail it doesn't delete anywhere else, if I move an e-mail on one computer it's not moved on anything else. I believe this is a POP issue. Does Yahoo biz mail allow you to switch to IMAP and would this fix my problem or should I try and switch the account over to GMAIL since I know it can handle this and if so what is the best process (export all e-mails, import and have them show on all 3 mac devices). Thanks for the help! ---EDIT---- Found this link: http://mail.google.com/mail/help/intl/en/switch.html#why Main question is if I do this will it allow me to keep my @mycompany.com or will my new address be @gmail.com?
