Exchange Online vs. Office 365: Which plan is a better fit?

Many organizations do a very narrow cloud migration and will just shift the messaging platform to Exchange Online. Some of the basic Office 365 plans cost just an additional dollar per user, per month to move from Exchange Online Plan 1 ($4 per user, per month) to Office 365 Business Essentials ($5 per user, per month). An organization that does not want to spend a relatively small amount will miss out on a number of valuable collaboration services that can help end users do more with the platform, such as Microsoft Teams, Skype for Business, SharePoint, OneDrive, Office Online Apps, Forms, PowerApps, Flow and Bookings.
