Can I cancel my subscription at any time?
You can cancel your subscription at any time. For annual commitment subscriptions, such as Office 365 Enterprise E5, there is a penalty for canceling before the end of your contract. Read the complete
Microsoft Online Subscription Agreement.
What happens to my data if I cancel my subscription?
Your data is yours. If you decide to cancel your Office 365 subscription, you can download your data—for example, your email and documents on team sites—and save it to another location.

Yes. If you purchase an Office 365 subscription with the same number of user accounts you created by the end of your free trial, the information and configuration for these users' accounts will remain intact.

Your desktop version of Office is also automatically kept up to date and upgraded when you connect to the Internet, so you always have the latest tools to help you work.
