Dear @Mark Connell,
Thank you for contacting the Microsoft 365 Q&A forum community support team. That error code ("NOOUTLOOKPROPLUS") indicates that the Microsoft 365 subscription tied to your account does not include a desktop Outlook license, or the license hasn’t been properly activated on your new device.
Let’s resolve this step by step:
Step 1: Verify your subscription covers desktop Outlook
- Only plans such as Business Standard, Business Premium, E3/E5, etc., include the desktop version of Outlook.
- Log into My account > Subscriptions to confirm if desktop apps are included. If not, you’ll need to upgrade your plan.
Step 2: Ensure correct license assignment
- If you’re using a work or school subscription, check via the Microsoft 365 Admin Center (please note that if you are a user you will need to ask your global administrator to perform these steps) that your user account is assigned a license that includes Office desktop apps.
For a visual guide, see Microsoft's official support documentation: You Currently Have Not Been Assigned an Office License that Includes the Office Desktop Apps
- After confirming, sign out of Office on laptop2, then sign back in with the same account to refresh the license information.

Step 3: Set the account as the primary in New Outlook
- In the New Outlook, the first/primary account determines desktop access for others.
- If you have multiple accounts configured, ensure that the one with the valid desktop license is set as primary.
Step 4: Repair activation if needed
On laptop2:
- Close Outlook and all Office apps.
- Open Setting > App > Installed apps
- Find Outlook for Window and right-click on it and select Advanced option.
- Choose Repair Option.
- Restart your computer after the repair is complete.
- This process will fix most common issues with OutlooK Office apps without affecting your personal files.
Step 5: Ensure Outlook is updated
- In the Microsoft Store, go to Downloads & updates and check for updates to New Outlook.
- Restart Outlook to apply any updates.
I truly hope you understand that the initial steps I suggested may not have completely resolved the issue, as there might still be underlying causes, we haven't uncovered yet. Please know that I’m here with you every step of the way, ready to work together and do everything I can to help troubleshoot and find the best solution.
Once configured correctly, Outlook should activate on your new device automatically. Feel free to share any updates or screenshots if the issue persists. I’m here to help you navigate this!
