- Office 365 Enterprise E3 Vs Microsoft 365 E3
Microsoft 365 Business Premium has everything you need for your small business, combining the best-in-class cloud-based productivity apps with simple device management and security that enable your employees to do their best work. In some cases, however, you may need to migrate your Microsoft 365 Business Premium subscription to Microsoft 365 E3.
For example, your business has grown and needs more than 300 licenses (congratulations, by the way).
Overall, the biggest difference between Office 365 E1 and E3 is that E3 is better for remote workers. The biggest difference between E3 and E5 is that E5 has extra security and analytics. Here’s a detailed breakdown of pricing and the key Office 365 features for each Enterprise plan: Which One Is Right for You? Office 365 E3 is a cloud-based suite of productivity apps and services with information protection and compliance capabilities included. Install Office mobile apps on up to five PCs or Macs, five tablets, and five phones per user. Protect information with message encryption, rights management, and data loss prevention for email and files.
Or, your business needs enterprise features, such as Microsoft 365 Apps for enterprise, Windows 10 Enterprise E3, or Enterprise Client Access Licenses (CALs).
Upgrading is easy: you can start the upgrade from the Admin center. All your data and configuration in your current subscription is maintained. There's nothing for you to do to prepare for the migration and nothing to do afterward, except take advantage of the new features.
Note
You can also use a Microsoft 365 Business Premium subscription for up to 300 seats and get a Microsoft 365 E3 subscription for more than 300 seats. However, Microsoft Defender for Office 365 is not included with Microsoft 365 E3. For continued threat protection, you should add additional Defender for Office 365 licenses so that all of the users in scope of your Defender for Office 365 polices are licensed.

- Group Policy support
- Spreadsheet compare and inquire
- Business intelligence
OneDrive for work and school accounts is online storage space in the cloud that's provided for individual licensed users in an organization. Use it to help protect work files and access them across multiple devices. OneDrive lets you share files and collaborate on documents, and sync files to your computer. Learn more about OneDrive features, functionality, and pricing.
OneDrive is included in Microsoft 365 and Office 365 plans, in SharePoint plans, and can also be purchased as a standalone plan.
For detailed plan information on subscriptions that enable users for OneDrive, see the full subscription comparison table and Compare OneDrive for Business plans.
Note
OneDrive standalone plans include Office for the web.

Note
You must assign at least one license to a user before you can increase the default OneDrive storage space.
When you need cloud storage for individual users beyond the initial 5 TB, admins can open a case with Microsoft technical support to request it. Additional cloud storage will be granted as follows:
When a user has filled their 5 TB of OneDrive storage to at least 90% capacity, Microsoft will increase your default storage space in OneDrive to up to 25 TB per user (admins may set a lower per user limit if they want to).
For any user that reaches at least 90% capacity of their 25 TB of OneDrive storage, additional cloud storage will be provided as 25 TB SharePoint team sites to individual users. Contact Microsoft technical support for information and assistance.
To see the storage space and usage for an individual user, go to Manage storage in the OneDrive sync app. To see how much storage users across the organization are using, go to the OneDrive usage report in the Microsoft 365 admin center.
Supported uses
OneDrive storage is provisioned on a per user basis and is designed to serve the needs of individual users.
Storage of data other than an individual user's work files, including system back-ups and departmental and organizational level data, is not supported, nor is the assignment of a per user license to a bot, department, or other non-human entity. SharePoint is the best solution for more advanced content management and collaboration, including storing and managing files, communications, and intranet sites across a team or organization.
OneDrive limits
To learn about file and sync limits, see SharePoint limits and Invalid file names and file types.
For plans that include unlimited cloud storage for individual users, note that limits may apply on non-storage features.
