Understand Outlook Desktop Licensing for Exchange Online

Clarify how Outlook desktop licenses apply to Exchange Online Plan 2 and Business Basic accounts.

Exchange Online Plan 2 and Business Basic provide hosted email services but do not include a license for the Outlook desktop application.

If you are able to use the Outlook desktop app with these accounts, it means the application is licensed through a separate Microsoft 365 plan (such as Business Standard) or a standalone Office purchase. Once the software is licensed on your device, it can connect to any valid Exchange account.

Check your installed Office license

Open your Outlook desktop application, click on 'File' in the top-left corner, and navigate to 'Office Account'.

Review subscription details

Under 'Product Information', you will see the specific Microsoft 365 plan or standalone license that is activating your desktop software.

Upgrade if necessary

If you need to license desktop Office for a user who only has Business Basic, consider upgrading their plan to Microsoft 365 Business Standard or higher.

Account Connectivity: A single licensed installation of Outlook can connect to multiple email accounts simultaneously, regardless of the individual license level of those email accounts.

Yes, but only if you already have the Outlook desktop application licensed and installed through another standalone purchase or a premium Microsoft 365 plan (like Business Standard).
