Are there limitations regarding the number of e-mail messages I can send? What is Hosted Exchange? What’s the difference between a web hosting e-mail and Microsoft Hosted Exchange e-mail? What is the maximum size of an e-mail message that I can send and receive? How is the Hosted Exchange service paid for? Can I access the service using an Internet browser? Do you check e-mail for viruses and spam or do I need to use my own antivirus software? I’m currently using POP3/IMAP account or webmail, can I migrate my existing e-mail? Where is my data (e-mail, calendars, contacts, documents) stored? I’m using Outlook with a POP3/IMAP account; how would I benefit from Hosted Exchange?
