Today's business users want more intuitive technology, uninterrupted services, and the freedom to work when and where they need to. Office 365 helps take location out of the equation so that your employees can live life on their terms.

Connected people are productive people

Office 365 keeps people connected to one another, and to documents and data. Intuitive tools for online meetings, file storage and sharing, and team collaboration make it easy to connect and collaborate with colleagues whenever, wherever.

Emails and calendar on the go

Did you know Office 365 is the one destination for email, calendars, files, contacts and tasks? During your morning train commute you can coordinate meetings on the go, access synchronized contacts, check your task list and use intelligent tools to manage your inbox so you can quickly deal with the most important matters.

Anti-spam and anti-malware protection

Office 365 applies a layer of anti-spam and anti-malware protection across a global network of datacenters to prevent infection via email. And your employees have control over their spam-quarantined messages.

  2. When deciding which projects to start with, prioritize those that you know will be easier to implement and will have a positive impact on the business.
  3. Ensure your teams understand the "What's in it for me?", such as reducing the amount of time spent looking for the most up to date document or allowing multiple team members to edit a document at a time.

OneDrive for Business lets your team collaborate on documents, share reports with partners, and connect with customers—from virtually any device. You can enable everyone to work on the same files—simultaneously—and track everyone's changes in real time. Keep reviewing and refining your files online and offline, at your desk or on the go.

Skype for Business makes it easy for people to meet and connect online, from wherever they are, on multiple devices.

  2. Encourage employees to use Skype for Business for all meetings, and make the most of rich communication and collaboration functions like high-definition video, desktop sharing and OneNote for shared meeting notes. Direct employees to the Lync/Skype for Business mobile app for iOS, Android and Windows to stay connected and attend meetings from anywhere.

Bring your team together

Yammer helps your organization listen, adapt, and grow in new ways by working like a network. More than a content repository, it's a place where your teams can discuss various aspects of a project, share ideas, give feedback, take notes together, review the same documents, and much more. Yammer makes connecting your distributed workforce easy. It helps employees get answers to questions faster with an open community feed. And most importantly, it inspires unity and innovation by allowing people to learn, share, and be heard.

Launch your Yammer network

Using Yammer enables people to easily share ideas and work together across geographies, cultures and functional teams. Yammer brings teams across a company together, making it possible to tap into the knowledge that exists within their organization and build on the work of others.

Video tutorial
Join the conversation

Some of the best ideas come from spontaneous conversations, with people you never expected. That's why Yammer is built around open communication – where people work in the open, conversations only happen in private when they need to and everyone benefits from shared information.

Share your knowledge

Yammer gives you a voice to share your knowledge and skills with others so you can make the most out of what you know. It starts with your Yammer profile. Complete your profile so coworkers can discover who you are, what you’re working on and how you can work together.

Discover what you need

Everyone holds a wealth of information—expertise in a specific area, content created for a project or insights from previous experiences. Yammer lets you discover things you wouldn’t have found otherwise: the right people, documents and conversations you need to get your best work done.

Listen to the conversations that matter

Connect your organization to boost engagement and surface important information and experts. Yammer users gain 76% more visibility into other departments or locations, and 80% are more informed with what is happening inside their organization.

Grow your business

Drive innovation, get to market faster and deliver experiences that grow customer loyalty with Yammer. Among business leaders of networked organizations, 93% agree that Enterprise Social tools stimulate innovation in their companies.

Adapt and make smarter decisions

Open collaboration is more efficient collaboration. Yammer helps teams quickly adapt to change and work together more productively. 71% of business leaders report that Enterprise Social tools increase the speed of access to knowledge.

  1. Easily embed a Yammer feed into other enterprise applications your organization is using, such as an intranet or SharePoint team sites, so that employees can access and respond to Yammer conversations from whichever platform they're using.
  2. You can also get your executives and leadership teams involved by incorporating Yammer into an all-company meeting or event.
  3. Oftentimes called a "YamJam," employees can submit their questions and comments to a designated Yammer group where executives can then provide responses and updates in real-time.


The pace of business communication has increased due to online technologies, most specifically social networking. As such, Office 365 has evolved to a more social suite. For example, Yammer, an Enterprise Social Network (ESN) helps your organization listen, adapt, and grow in new ways by working like a network.

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.
