Frequently asked questions
Office 365 Enterprise E1 works best with the new Office, Office 2010, and Office 2011 for Mac. Office 365 works with slightly limited functionality with Office 2007. You do not need a desktop version of Office to use Enterprise E1. However, you will receive a much richer experience and be able to work offline if you do connect a desktop version of Office to the Office 365 services.
You can pay with all major credit cards, and your subscription amount will appear on your credit card statement. You also have the option to receive an invoice and, depending on your choice of services, you will be billed monthly or annually. You receive an email message when your invoice is ready to be viewed and, if a purchase order (PO) number is entered when you buy your subscription, that number is included in your invoice.
Yes, discounts are available for Office 365 enterprise agreement customers (typically 250+ licenses) who want to purchase through volume licensing. A Microsoft expert can help you explore the purchasing options for large enterprises and help you determine which is best for you. Learn more about volume licensing. Find a Microsoft expert.
You can cancel your subscription at any time. For subscriptions that are paid annually, such as Office 365 Enterprise E1, there is a penalty for canceling before the end of your contract. Read the complete Microsoft Online Subscription Agreement.
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. You should save your data before you cancel. After you cancel your subscription, data associated with your Office 365 account will be available to your administrator(s) in a limited function account for 90 days.
You can transition your account within service families, for example, from Office 365 Small Business to Office 365 Small Business Premium, or from Office 365 Enterprise E1 to Office 365 Enterprise E3 or E4. You cannot transition between Office 365 service families, that is, from an Office 365 Small Business plan to Office 365 Midsize Business or an Office 365 Enterprise plan, or vice versa. In order to change from a plan in one service family to another (for example, from a Small Business plan to the Midsize Business plan, or from the Midsize Business plan to an Enterprise plan), you must first cancel your account with the plan you currently have, and then sign up for a different one.
Note on domain names when you transition or change your account:
- When you transition your account within a service family, your domain name is transferred to your new account, whether you brought your own domain name to the Office 365 account or you set up a domain name with Office 365.
- When you change to a plan in a different service family:
- If you brought your own domain name to use with Office 365, that domain name will be available as soon as you sign up for your new subscription plan.
- If you set up a yourcompany.onmicrosoft.com domain name with your Office 365 account, you have to wait 90 – 180 days before that name is available for your new subscription plan. If someone else has taken the yourcompany.onmicrosoft.com domain name during that time, you can’t use it.
Get more details about domain names and how to transition your plan within a plan family or change your plan to a different service family.
You can mix Office 365 plans only within their respective service families. Office 365 Small Business can be combined with Office 365 Small Business Premium, for example, but not with Office 365 Midsize Business, the Office 365 Enterprise plans, or the standalone offers, such as Exchange Online. The same applies to Office 365 Midsize Business, which cannot be combined with Office 365 Small Business plans, Enterprise plans, or the standalone offers.
Customers who want the greatest flexibility can purchase Office 365 Enterprise plans, which enable you to combine the Office 365 Enterprise E1, E3, and E4 plans, the Office 365 Enterprise K1 plan (for kiosk workers), and the full range of standalone offers (for example, Exchange Online, SharePoint Online, and Lync Online).
