if u want ur working email account on ur BB handheld and the BB device is ur personal the best Service that u can use is BIS(blackberry Internet Services) from ur carrier. so if ur IT-Manager ask about the licence u can tell him about the BIS. if ur IT use POP3 or IMAP or OWA u just add ur working email account it will automatically athinticate and now u recive ur emails on ur handheld. more BIS is for the Single one u can add ur 10-email account e.g yahoo, gmail, and hotmail too if it is payed.
Regards,
