A: POP3 servers can only manage to emails and not contacts, calendars, or tasks. Your email client will still receive meeting requests or contacts, but should the information change, you won't know. Worse yet, if the data on your PC is lost or damaged, your email, calendar and contacts will be too. By leveraging the power of Logical Net's Hosted Microsoft Exchange®, your data is stored on the secure Exchange server, giving you the convenience of checking your information from any PC.
