Frequently Asked Questions

Do I automatically get a refund when upgrading a Microsoft 365 plan?

Not always. While some upgrades automatically apply a prorated credit to your next billing cycle, it is highly recommended to contact billing support to verify your specific account terms and ensure the unused portion is credited properly.

Where can I find my subscription invoice to request a refund?

You can view and download your past invoices by logging into the Microsoft 365 admin center, navigating to the 'Billing' section on the left menu, and selecting 'Bills & payments'.

How long does it take for a Microsoft subscription refund to process?

Once your prorated refund is approved by Microsoft Support, it typically takes a few business days to process. However, it may take up to 1-2 billing cycles for the credit to formally reflect on your bank statement.

Can I downgrade my Microsoft 365 plan instead of upgrading?

Yes, but downgrading might incur early cancellation fees depending on your commitment term, and could result in a loss of certain features. You must manage this through the admin center or by contacting support prior to your next billing date.
