Services tailored to your business

Your business is unique, with its own set of needs. Office 365 gives you the flexibility to get exactly the services you want, which saves you costs. You can combine Office 365 with your existing investments, like previous versions of Office, and connect users directly from their familiar applications. If you have users with different needs, you can mix and match services for them, so you can provide the tools to those who need them in a cost-effective way.

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.

Annual commitment payment is available for Office 365 Enterprise plans. With annual commitment, you sign up for a one-year subscription, but you can choose to pay month to month or pay for the entire year at the time you sign up.

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 annual commitment subscriptions, such as 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.

Yes. If you need to upgrade, you can transition your account to a different plan. You can upgrade your account within a service family (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), or you can upgrade to a plan in a different Office 365 service family (for example, from a Small Business plan to the Midsize plan or an Enterprise plan, or from the Midsize plan to an Enterprise plan). You can also upgrade from the Exchange Online standalone plans to an Enterprise plan.

In most cases, you can use the Switch plans wizard in your Admin center to upgrade your plan. If your subscription has more than 300 users or if you used a prepaid card to purchase your plan, the Switch plans wizard is not available. Plans that are not eligible for the Switch plans wizard can be upgraded manually. Learn more about upgrading Office 365 plans.

NOTE: When you upgrade your account, 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.

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).

Microsoft experts are trained IT and development companies that can help you move to Office 365 or develop custom solutions for your business. You can find a listing of all of our Microsoft experts in Microsoft Pinpoint.
