Fix Work or School License Does Not Enable Outlook for Windows
Question details
The user is unable to access Outlook for Windows because the application throws an error stating that their work or school license does not enable access.
- Product
- Outlook for Windows / Office Professional Plus 2019
- Device & OS
- Windows
- Scenario
- The user is trying to check their email on a secondary laptop, or is being forced to transition from Windows Mail to the New Outlook application.
- Observed behavior
- Outlook blocks access due to licensing constraints, whereas the previous Windows Mail app functioned without issue before redirecting to the New Outlook.
Ensure you know which version of Office you are licensed for (e.g., Office Professional Plus 2019 vs. Microsoft 365) and whether your account has administrative access to check device limits.
Verify Your License Assignment and Device Limits
Check your Microsoft account to ensure your license covers the device you are currently using, as Office 2019 is limited to a single PC.
Office Professional Plus 2019 is typically a perpetual license intended for only one activated computer. In contrast, Microsoft 365 subscriptions allow for activation across multiple devices. When Windows Mail redirects to the New Outlook, it enforces stricter licensing checks that immediately flag secondary devices using a single-device license.
Navigate to the Microsoft account web portal and log in using the work or school account associated with your Office purchase.
Click on 'Services & subscriptions' from the navigation menu to view your active Microsoft products and licenses.
Expand your Office 2019 or Microsoft 365 details to see the devices currently activated. If your limit is reached, select 'Sign out' or 'Deactivate' on an old device to free up the license for your current laptop.
If you are using a school or corporate account and cannot manage the devices yourself, contact your organization's Microsoft 365 administrator to request a license upgrade or remote device deactivation.
Revert to Classic Outlook or Windows Mail
Temporarily roll back the automatic transition to the New Outlook to regain access to your emails without triggering the new license blocks.

Frequently Asked Questions
Why does New Outlook say my work or school account is not supported?
The New Outlook for Windows requires specific Microsoft 365 subscription plans or compatible enterprise licenses. Standard perpetual licenses like Office Professional Plus 2019 may not include the multi-device cloud entitlements required to run the new application on a secondary PC.
Can I install Office Professional Plus 2019 on multiple computers?
No. Office Professional Plus 2019 is a perpetual license typically restricted to a single activated computer at a time. To use Office applications on multiple devices simultaneously, a Microsoft 365 subscription plan is required.
How do I stop Windows Mail from constantly redirecting to New Outlook?
You can temporarily disable the redirect by turning off the 'New Outlook' toggle located in the top-right corner of the app. Keep in mind that Microsoft is permanently phasing out Windows Mail, so this workaround will eventually stop functioning.
