In 2017, Microsoft 365 introduced a business suite containing several well-known tools under one license - including Office 365.
Office 365 is a cloud-based suite of apps such as Word, Excel, PowerPoint, Outlook, SharePoint, Teams, etc., with the primary function of supporting business and employee productivity. The content of applications depends on the subscription plan selected.
Microsoft 365 is a broader umbrella that, in addition to Office 365, also covers a wide range of services such as Windows 10 Enterprise, Enterprise Mobility + Security (EMS), and machine learning. Microsoft 365, like Office 365, is built on separate subscription-based licenses. Each subscription package also includes different functionality levels, e.g., Microsoft Teams, Sharepoint, OneDrive, etc.
To add to the confusion, Microsoft's productivity suite Office 365 changed its name to Microsoft 365, but without any noticeable changes to the existing subscriptions.
However, we at Fellowmind will guide you through the jungle of subscriptions and help you choose the most suitable one based on your project requirements.
