Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
If the subscription was upgraded to Microsoft 365 Business Standard, the desktop apps should be included. On Mac, the most common causes are that Office is still activated with the wrong license, the apps have not been updated, or the Mac cannot run the required Office version.
Try this in order:
- Confirm the plan includes desktop apps Microsoft 365 Business Standard includes the desktop versions of Outlook, Word, Excel, PowerPoint, and OneNote.
- Update Office on the iMac In any Office app, select Help > Check for Updates. In Microsoft AutoUpdate, select Update or Update All. Restart the app after the update finishes.
- Check for wrong license activation on Mac If Office was previously activated with another license, or with a one-time Office for Mac purchase, the apps can stay in a limited state. In that case, remove the Office license files and reactivate so Microsoft 365 benefits apply.
- Sign in again with the upgraded account After reactivation, sign in with the work account that has the Business Standard license assigned.
- Check macOS compatibility
If the iMac cannot support the required macOS version, the latest Office updates cannot be installed. In that case, the supported options are:
- use Microsoft 365 on the web
- install Office on another supported device
- upgrade the device
If Outlook on Mac shows a license error specifically, the work account must have a license that includes desktop apps. Business Standard is one of the supported licenses.
