You don't need to install anything in order to use Office 365. To help you easily connect your desktop version of the latest version of Office, Office 2013, Office 2010, or Office 2007 to Office 365, Microsoft provides Office 365 customers an installable piece of software—called “Office Desktop Setup”—at no charge.

Office Desktop Setup provides many benefits, including:

  • Automatically detecting necessary updates.
  • Installing updates and components upon approval or silently from a command line.
  • Automatically configuring Outlook and Microsoft Skype for Business for use with Microsoft Office 365.
  • Uninstalling itself from the client computer after running.

You can find and install Office Desktop Setup in your Office 365 administration center. If your plan includes a subscription to Office, you will also be able to install that directly from the Office 365 administration center.

Office 365 Setup provides step-by-step guidance. In just a few quick steps you can sign up for Office 365, set up your organization's domain name and add user accounts, install Office, and move your existing email to Office 365.

You can pay with all major credit cards, and your subscription amount will appear on your credit card statement. For Office 365 Enterprise, Office 365 Business, 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 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.

Yes. If you need to upgrade, you can transition your account to a different plan. For example, you can upgrade from an Office 365 Business plan to an Office 365 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.
