Frequently asked questions

Office 365 Small Business supports a maximum of 25 users. If you have more than 25 users or think you will soon you might want to consider Office 365 Enterprise E1.

Office 365 Small Business works best with the latest version of 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 Office 365 Small Business. 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 can cancel your subscription at any time. However, depending on the product and the type of subscription you have, there may be a penalty for canceling before the end of your contract. For subscriptions with a month-to-month commitment, there is no penalty for cancelling your contract at any time. Subscriptions with an annual commitment may incur some penalties if canceled early. Office 365 Small Business subscriptions are available as a month-to-month commitment or as an annual commitment. 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).

You can add the domain name you own to Office 365 to create both domain-based email addresses and a public-facing website. Find your domain registrar or DNS hosting provider. Compare domain management in Office 365 subscriptions.

“The cloud" is a friendly way of describing web-based computing services that are hosted outside of your organization. When you use cloud-based services, your IT infrastructure resides off your property (off-premises), and is maintained by a third party (hosted), instead of residing on a server at your home or business (on-premises) that you maintain. With Office 365, for example, information storage, computation, and software are located and managed remotely on servers owned by Microsoft. Many services you use every day are a part of the cloud—everything from web-based email to mobile banking and online photo storage. Because this infrastructure is located online or “in the cloud,” you can access it anywhere, from a desktop, PC, laptop, tablet, smartphone, or other device with an Internet connection.
