And teams can join online meetings with HD video and screen sharing from anywhere or connect fast with social networking.

Compliance simplified, with enhanced data protection

Office 365 simplifies compliance by enabling you to archive, use in-place legal hold, and find the documents you need fast by searching across mailboxes, team sites, and recorded meetings. It also helps you protect your company’s data. You can create your own data loss prevention policies and use built-in policy education in email to inform users what they’re doing wrong before they send a message. That way your data stays safe and your users stay up to date with company policies.

Advanced IT controls without the maintenance overhead

Give your IT freedom, flexibility, and control while reducing your IT overhead. Stop managing servers and get guaranteed 99.9% uptime. Move to the cloud on your terms. Connect your on-premises servers to Office 365 and run the latest version of Office side by side with a previous version while users transition. Stay in control and save time by managing your services easily in the admin center from any browser and by automating management tasks using PowerShell commands.

Frequently asked questions

You can pay with all major credit cards, and your subscription amount will appear on your credit card statement. For Office 365 Enterprise, Midsize, and standalone plans, you 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 customers (typically 250+ licenses) who want to purchase through volume licensing. A Microsoft expert can help you explore the purchasing options for larger organizations 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 E3, there may be 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. 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).

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. Once your free trial expires, you won't be able to continue using Office 365 for free. You will have an additional 30 days to purchase Office 365 before your account information is erased. Once your trial account information has been erased, it cannot be retrieved.

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.

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.

Internet access is required to install and activate all Office 365 plans and to manage your subscription account. Internet connectivity is also required to access Office 365 cloud productivity services, including email, conferencing, IT management, and other services.

Many Office 365 plans also include the desktop version of Office, for example, Office 365 Small Business Premium and Office 365 Enterprise E3. One of the benefits of having the desktop version of Office applications is that you can work offline and have the confidence that the next time you connect to the Internet all your work will automatically sync, so you never have to worry about your documents being up to date. 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. Compare Office 365 plans.
