How to Configure Microsoft 365 Viewer Mode Without Disabling Outlook
Question details
The organization needs to configure Microsoft 365 Viewer Mode for unlicensed users on shared computers without restricting Outlook access for licensed users.

- Product
- Microsoft 365 Apps for enterprise
- Device & OS
- not provided
- Scenario
- Sharing computers between licensed and unlicensed users where unlicensed users need to view documents while licensed users require full Outlook functionality.
- Observed behavior
- Administrators need to ensure that enabling Viewer Mode does not disable or restrict Outlook for users who have an active license on the shared machine.
Ensure you have administrative privileges to access the Group Policy Management Console (GPMC) and that the latest Microsoft 365 Administrative Templates are installed.
Enable Viewer Mode via Group Policy
Use Windows Group Policy to deploy Viewer Mode, which automatically detects active licenses and retains full Outlook functionality for licensed accounts.
Microsoft 365 Viewer Mode is designed to work dynamically in shared environments. When enabled through Group Policy, it suppresses activation prompts for unlicensed users opening Word, Excel, and PowerPoint files. Importantly, if a user logs in with a valid Microsoft 365 license, all applications, including Outlook, remain fully functional without needing manual exclusions.
Press the Windows key + R, type 'gpmc.msc' into the Run dialog, and press Enter to launch the Group Policy Management Console.
In the left pane, navigate to Computer Configuration > Policies > Administrative Templates > Microsoft Office 2016 (Machine) > Licensing Settings.
Locate the policy named 'Use Viewer Mode'. Double-click it, select the 'Enabled' radio button, and click 'Apply' then 'OK' to save the settings.
Open Command Prompt as an administrator on the shared computers and run 'gpupdate /force' to apply the new Viewer Mode settings immediately.

Provide Seamless Document Viewing and Editing with WPS Office
If managing complex Microsoft 365 licensing policies on shared computers is becoming a hassle, consider installing WPS Office. It provides a lightweight, free alternative that natively supports Word, Excel, and PowerPoint formats without requiring complicated Viewer Mode configurations for unlicensed users.
- 1. Download WPS Office: Visit the official WPS Office website and download the free installer.
- 2. Install on Shared Computers: Run the setup file and install the application across the shared workstations for all users.
- 3. Open and View Documents Easily: Users can immediately open, view, and edit Microsoft Office documents without needing an assigned enterprise license.

Frequently Asked Questions
Will enabling Viewer Mode restrict licensed users from sending emails in Outlook?
No. Viewer Mode only applies to unlicensed products. If a user logs into a shared computer and possesses a valid license for Microsoft 365, Outlook and all other Office applications will remain fully functional for them.
Do I need to manually exclude Outlook from the Viewer Mode policy?
Manual exclusion is not necessary. The 'Use Viewer Mode' Group Policy is designed to automatically recognize when a user has a valid license, allowing Outlook to operate normally without additional exclusion rules.
Why are unlicensed users still getting activation prompts after enabling Viewer Mode?
If prompts persist, the Group Policy may not have been updated on the local machine. Run 'gpupdate /force' in the Command Prompt to refresh policies, and ensure that the 'Use Viewer Mode' setting is correctly applied to the computer object in Active Directory.
Where can I get advanced help for Windows Group Policy configurations?
For highly specific Group Policy troubleshooting, it is recommended to consult the Microsoft Q&A forums and tag your post with the 'Windows Group Policy' tag to reach system administration experts.
