The user needs to resolve recurrent Microsoft Office activation failures occurring on a Remote Desktop Services (RDS) server.

How to Fix Office Activation Errors on an RDS Server

Product: Microsoft Office 365
Device & OS: not provided
Scenario: Deploying and using Microsoft Office applications on a shared Remote Desktop Services (RDS) environment.
Observed behavior: Office activation fails within a few days on the RDS server, even though the user remains correctly signed into their Microsoft account.

Before you start

Ensure you have administrative privileges for the RDS server and access to the Microsoft 365 admin center to review licensing and deployment configurations.

Solution 1Recommended

Enable and Verify Shared Computer Activation

Confirm that your Microsoft 365 subscription supports shared computer activation and ensure it is properly configured on the RDS deployment.

In a Remote Desktop Services environment, standard Office activation will fail because multiple users are accessing the same installation. Shared computer activation allows you to deploy Microsoft 365 Apps to shared environments without triggering device installation limits.

Verify subscription plan

Log into the Microsoft 365 admin center and confirm your plan supports shared computer activation. Supported plans typically include Microsoft 365 Apps for enterprise and Office 365 E3/E5.

Modify the deployment configuration

If you are using the Office Deployment Tool (ODT), open your configuration.xml file and ensure the property `<Property Name="SharedComputerLicensing" Value="1" />` is included.

Check the Registry Editor

On the RDS server, open the Registry Editor (regedit.exe) and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration. Verify that the 'SharedComputerLicensing' string is set to a value of 1.

Enable and Verify Shared Computer Activation

Licensing Requirement: Microsoft 365 Apps for business and most personal plans do not support shared computer activation.

Solution 2

Run the Microsoft Support and Recovery Assistant

Use Microsoft's official diagnostic tool to automatically detect and repair activation problems on the server.

Frequently Asked Questions

Which Microsoft 365 plans support shared computer activation?

Shared computer activation is typically supported by Microsoft 365 Apps for enterprise, Office 365 E3/E5, and Microsoft 365 Business Premium. Plans like Microsoft 365 Business Standard or Apps for business generally do not support this feature.

Why does Office keep asking for activation on my RDS server?

If shared computer activation is not enabled, Office attempts to activate using standard licensing. In an RDS environment, this fails quickly because multiple virtual sessions cause the software to think it is being installed on too many different devices, exceeding the per-user device installation limit.

How do I verify if shared computer activation is currently enabled?

You can verify this by opening the Registry Editor on your RDS server. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration and look for the 'SharedComputerLicensing' string. If the value is set to 1, the feature is enabled.
