Question details

Administrators need to completely block users from independently starting trials for Microsoft 365 products when the standard tenant trial setting is already disabled.

How to Prevent Users from Starting Microsoft 365 Trials When Disabled

Product: Microsoft 365
Device & OS: not provided
Scenario: Managing user permissions and self-service license acquisition in the Microsoft 365 Admin Center.
Observed behavior: Users are still able to sign up for self-service trials (such as Planner Plan 3) despite the administrator disabling the 'Let users start trials on behalf of your organization' setting.

Before you start

Ensure you are logged in as a Global Administrator or Billing Administrator and have administrative access to Windows PowerShell to manage self-service commerce settings.

Solution 1Recommended

Disable Self-Service Purchases via PowerShell

Use this solution to specifically block individual users from bypassing tenant settings through self-service purchase and trial mechanisms.

The setting 'Let users start trials on behalf of your organization' only governs organization-wide trials. Individual self-service trials are controlled separately by the MSCommerce PowerShell module, which allows administrators to disable specific self-service product policies.

Open Windows PowerShell as Administrator

Right-click the Start button, select Windows PowerShell (Admin), and run 'Install-Module -Name MSCommerce' to install the required module.

Connect to MSCommerce

Type 'Connect-MSCommerce' and press Enter. A prompt will appear asking you to log in with your Microsoft 365 Global Administrator credentials.

Identify Self-Service Products

Run the command 'Get-MSCommerceProductPolicies -PolicyId AllowSelfServicePurchase' to view a list of all products and their current self-service trial status.

Disable the Policy

To disable self-service trials for a specific product, run 'Update-MSCommerceProductPolicy -PolicyId AllowSelfServicePurchase -ProductId <ProductID> -Enabled $False', replacing <ProductID> with the ID found in the previous step.

Disable Self-Service Purchases via PowerShell

Policy Application Delay: It may take up to 24 hours for self-service purchase and trial policy changes to fully replicate and take effect across your Microsoft 365 tenant.

Solution 2

Review Office Store Access Settings

This method prevents users from acquiring third-party trial apps and additional add-ins from the Microsoft Store.

Frequently Asked Questions

Why does the 'Let users start trials' setting not block all trials?

This specific setting only prevents users from starting trials on behalf of the entire organization. Individual users can still sign up for independent self-service trials unless explicitly blocked via the MSCommerce PowerShell module.

Does disabling Office Store access stop trial sign-ups?

Disabling Office Store access stops users from installing third-party apps and certain add-ins, but it does not block first-party Microsoft self-service trial sign-ups such as Planner, Visio, or Project.

Will users lose access to their active trials if I disable the setting?

Disabling the self-service trial setting prevents new trial sign-ups. Existing active trials may remain operational until they expire naturally, at which point the user will lose access unless an administrator assigns a paid license.

How can I check which users have started independent trials?

You can view active self-service subscriptions by navigating to the Microsoft 365 Admin Center, selecting 'Billing', and then clicking 'Your products'. Self-service purchases will be listed alongside standard organizational licenses.
