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