To request a refund for Microsoft 365, you need to follow specific procedures based on your billing account type. If you have an MCA billing account, you can receive a prorated credit or refund if you cancel within seven days of the subscription start or renewal. If more than seven days have passed, you will need to turn off recurring billing to prevent further charges, but you won't receive a refund for the initial payment.
If you have an MOSA billing account, you can also receive a prorated credit or refund after cancellation, which will be credited towards your next invoice or returned in the next billing cycle.
Since you mentioned that your computer is too old to install Microsoft 365, it is advisable to check your billing account type and follow the appropriate steps to request a refund. You may need to contact Microsoft support for assistance if you're unable to cancel your subscription directly.
Make sure to provide any necessary details, such as your account information and the reason for the refund request, when you reach out to support.
