What is Office 365?

Microsoft Office 365 for professionals and small businesses is a subscription service that combines Microsoft Desktop Apps available on your own computer with a set of web-enabled tools that are easy to learn and use. It also features Office on Demand, streaming live versions of your familiar productivity tools directly to any computer that has Internet access. This all works with your existing hardware, and comes backed by the robust security, reliability, and control you need to run your business.


Is Office 365 "Office in the cloud"?

With some Office 365 plans, you have access to familiar Office applications that are installed locally on your PC, but are downloaded and licensed from the cloud. When you're not at your own computer, you can stream live versions of the same applications to any computer that has Internet access. Or, you can use Office Web Apps from your tablet or smart phone. Office 365 service plans expand this experience by also featuring the latest versions of our cloud productivity services: Exchange Online, SharePoint Online, and Microsoft Teams. These familiar services combine to provide you with the most comprehensive productivity solutions for your business.


My enterprise/midsize business has advanced IT needs for reliability and user productivity. What does Office 365 provide?

Your businesses IT needs span a wide spectrum and that is why we offer a range of options. AppRiver offers several -- from basic email to a complete solution that includes full Office Professional Plus desktop software, along with Office on Demand and Office Web Apps. No matter what option you choose your business will benefit from the most advanced versions of Exchange Online, SharePoint Online, and Microsoft Teams, phone support 24 hours a day, seven days a week, and advanced IT controls that will provide your business with the solution you need.


I am a small business/professional. If I do not have IT expertise within my small business, can I still use Office 365?

Yes, and you’ve come to the right place to get it. AppRiver offers 24/7 Phenomenal Care at no extra charge to help you through any support issues that come up. Your team also will be using Office tools they are already familiar with and enjoying access from virtually anywhere to email, important documents, contacts, and calendars on nearly any device. In addition, Office 365 is backed by powerful security features, support 24 hours a day, and a 99.9% uptime guarantee to ensure your business has every tool it needs. Office 365 also offers a simple, monthly subscription packaged with an easy-to-use set of web-enabled tools for small businesses, independent consultants, and professionals. Check our pricing matrix to find out which Office 365 package option is the best fit for your business.


What does it mean to work from virtually anywhere and on nearly any device?

The Office 365 service offerings enable you to work with email, documents, and data from virtually anywhere and on nearly any device with a familiar productivity experience on PCs, phones, and in browsers. This means that an appropriate device, Internet connection, and supported versions of browsers are required. Access from mobile devices requires Wi-Fi capability or depends on carrier network availability. Keep in mind that some mobile functionality requires Office Mobile 2010, which is included with specific releases of Windows Phones and Nokia phones. Office Mobile 2010 is NOT included in Office 2010 applications, suites, or Web Apps. There are some differences between the features of Office Web Apps, Office Mobile 2010, and the Office 2010 applications.


What is Microsoft 365?

Microsoft 365 takes the familiar Office 365 Business and Enterprise plans and adds an upgraded Windows operating system license for current Windows users, all in a convenient, subscription package. Both Business and Enterprise versions of Microsoft 365 include additional device management capabilities and enhanced security framework. However, Enterprise versions include additional mobility and security features. Customers must be running Windows 7, 8, 8.1 Pro or later on their current desktops.


With Office 365 ProPlus from AppRiver, you get subscription-based, anywhere access to Microsoft's industry-leading office productivity software, including email, calendaring, IM, meeting, and other communication tools. Office 365 ProPlus includes all the great Office application experiences you expect.

The old software-from-a-box model meant that applications were tied to the computers they were installed on. Office 365 ProPlus allows people to access Office on up to 5 PCs or Macs and on their mobile devices. The new Office also works with smartphones, tablets, and in the cloud, even on PCs that don't have Office installed. So now you can always get to your important files, no matter where you are or what you're using.

With Office 365 ProPlus, you always have the latest versions of:

  • Use your Microsoft account to install Office
  • Stream your Office programs to another computer
  • Save files to OneDrive for easy access and sharing
  • Keep your personal settings wherever you are
  • Enjoy a consistent and familiar Office experience across PCs, Macs, Windows tablets, and most mobile devices
  • Use many of the same tools to deploy and configure Office 365 ProPlus that you're already using to deploy Office

Office Mobile

Office Mobile can be installed on up to 5 iPhones and Android phones, enabling you to access, edit, and view Word, Excel, and PowerPoint documents. Note that Office Mobile is already available on Windows Phones and does not count toward the 5-device limit. Use the OneNote, OWA, Microsoft Teams, and SharePoint Newsfeed apps on most devices. Stream full versions of Office programs on any PC with Office on Demand. (Works only with Windows 7 or newer on an Internet-connected PC and requires SharePoint Online or OneDrive. SharePoint and OneDrive are included in many Office 365 subscription plans.)
