What happens to my old e-mails? Not to worry. All of your messages will be retained and automatically transferred to your new account. Calendar appointments and contacts will also be transferred. You won't lose any valuable information.

How much storage space will my new account have? The current limit is 25GB.

What are the size limits for messages and attachments?The message size limit is currently 25MB, this includes the message header, message body, and any attachments. In the Outlook web app the maximum file attachment size is 10MB.

Is my information secure? Absolutely. Just like bank and credit card websites, Office 365 uses always-on HTTPS encryption to keep your mail secure, so someone sharing your favorite coffee shop's public Wi-Fi can't sneak a peek at your information.

Can I check my e-mail while abroad? Yes. Since your email is stored in the “cloud”, it is easily accessible from anywhere.
