Transform Your Business
Exchange Online
Microsoft Exchange Online is a hosted messaging solution that delivers the capabilities of Microsoft Exchange Server as a cloud-based service. It gives users access to email, calendar, contacts, and tasks from PCs, the web, and mobile devices. It integrates fully with Active Directory, enabling administrators to use group policies, as well as other administration tools, to manage Exchange Online features across their environment.
Office
Microsoft 365 is a subscription service that provides you with the latest version of the Office desktop applications that you’re already familiar with, such as Word, Excel, and PowerPoint.
Even though Office is a cloud-based service, Office applications don’t run in the cloud. Instead, users download Office applications from the Office 365 portal and install them on their local computers. Microsoft uses Click-to-Run technology to make the download and installation of Office applications fast and simple. Click-to-Run uses virtualization technology to run Office applications in a self-contained environment on a local computer, which allows users to run Office applications side-by-side with earlier versions of Office.

SharePoint
SharePoint in Microsoft 365 helps organizations share and manage content, knowledge, and applications to:
- Empower teamwork
- Quickly find information
- Seamlessly collaborate across the organization
Organizations use Microsoft SharePoint to create websites. You can use it as a secure place to store, organize, share, and access information from any device. All you need is a web browser, such as Microsoft Edge, Internet Explorer, Chrome, or Firefox.
SharePoint products and downloads
SharePoint can refer to one or more SharePoint products or technologies, including:
SharePoint in Microsoft 365 A cloud-based service, hosted by Microsoft, for businesses of all sizes. Instead of installing and deploying SharePoint Server on-premises, any business can subscribe to a Microsoft 365 plan or to the standalone SharePoint Online service. Your employees can create sites to share documents and information with colleagues, partners, and customers.
SharePoint Server Organizations can deploy and manage SharePoint Server on-premises or with an Office 365 Enterprise subscription to take advantage of all the latest features. And it offers additional features and capabilities, such as modern site pages, modern web parts and authoring, modern lists and libraries, modern search, integration with PowerApps, Power BI and MS Flow, and SharePoint home page.
SharePoint Designer 2013 A free program last released in 2013. Used to build powerful, workflow-enabled solutions. And used to edit external content types for an external data solution based on Business Connectivity Services.
OneDrive sync A desktop program that you can use to sync documents from a team site or OneDrive for work or school to your computer for offline use.
Power Apps
Power Apps is a suite of apps, services, and connectors, as well as a data platform, that provides a rapid development environment to build custom apps for your business needs. Using Power Apps, you can quickly build custom business apps that connect to your data stored either in the underlying data platform (Microsoft Dataverse) or in various online and on-premises data sources (such as SharePoint, Microsoft 365, Dynamics 365, SQL Server, and so on).
Apps built using Power Apps provide rich business logic and workflow capabilities to transform your manual business operations into digital, automated processes. What’s more, apps built using Power Apps have a responsive design and can run seamlessly in browser and on mobile devices (phone or tablet). Power Apps “democratizes” the business-app-building experience by enabling users to create feature-rich, custom business apps without writing code.
Power Apps also provides an extensible platform that lets pro developers programmatically interact with data and metadata, apply business logic, create custom connectors, and integrate with external data.
Power Apps for app makers/creators
Using Power Apps, you can create three types of apps: canvas, model-driven, and portal.
Power Apps for app users
You can run apps that you created, or that someone else created and shared with you, in browser or on mobile devices (phone or tablet).
Power Apps for admins
Power Apps administrators can use the Power Platform admin center to create and manage environments, view Dataverse analytics, and get real-time, self-help recommendations and support for Power Apps and Power Automate.
Power Apps for developers
Developers are app makers who can write code to extend business app creation and customization. Developers can use code to create data and metadata, apply server-side logic using Azure functions, plug-ins, and workflow extensions, apply client-side logic using JavaScript, integrate with external data using virtual entities and webhooks, build custom connectors, and embed apps into your website experiences to create integrated solutions.
Power Apps and Dynamics 365
Dynamics 365 apps (such as Dynamics 365 Sales, Dynamics 365 Customer Service, and Dynamics 365 Marketing) also use the underlying Dataverse platform used by Power Apps to store and secure data. This enables you to build apps using Power Apps and Dataverse directly against your core business data already used within Dynamics 365, without the need for integration.
