- Scenario
- Attempting to convert an active Microsoft 365 free trial into a Business Premium subscription within the admin center.

Purchase Business Premium Separately and Disable Trial Billing
Bypass the upgrade error by purchasing the Business Premium subscription as a standalone order, and then disabling the recurring billing on your trial to prevent double charges.
When a direct upgrade path is blocked by system restrictions, treating the upgrade as a new purchase within the same tenant is the official workaround recommended by Microsoft.
Log into the Microsoft 365 admin center. In the left navigation menu, go to 'Billing' and select 'Purchase services'.
Search for and select the 'Microsoft 365 Business Premium' plan. Click 'Details', input your required number of licenses and preferred billing frequency, then click 'Buy' to verify payment details and complete the order.
Navigate to 'Billing' > 'Your products' in the admin center. Click on your active Microsoft 365 trial subscription, select 'Edit recurring billing', choose 'Turn off', and save your changes.

Frequently Asked Questions
Why can't I upgrade my Microsoft 365 trial directly?
Certain trial plans restrict direct upgrades to specific subscription tiers due to billing system limitations, regional policies, or account mismatches. Purchasing a separate subscription is the standard workaround.
Will I lose my files if I switch from a trial to a new subscription?
No, your data is tied to your Microsoft 365 tenant and not just the specific trial license. As long as you purchase the new subscription within the same admin account, your files and emails remain safe.
What happens if I forget to turn off recurring billing for the trial?
If recurring billing is left on, Microsoft may automatically charge your payment method for the standard version of the trial plan once the free period ends, leading to duplicate and unnecessary subscription costs.
