Unable to renew expired subscription as won't let me change country in payment method following move

Because the subscription was originally purchased in the UK, the payment country for that subscription cannot be changed to France while that subscription still exists.

What to do:

1. Go to Services & subscriptions and confirm the old Microsoft 365 subscription status: https://account.microsoft.com/services
2. If it is still present, do not try to update that subscription with a French payment method.
3. If needed, cancel the old subscription or wait until it is fully gone/expired.
4. Update the Microsoft account profile country/region on the Your info page and make sure the account region is set correctly.
5. Then buy a new Microsoft 365 subscription for France using a French billing address and payment method.

Important details:

• Microsoft recommends changing region only when moving long-term.
• Items and subscriptions bought in one region might not work the same way in another region.
• If Microsoft 365 was bought from a third party instead of Microsoft, billing changes must be handled with that provider directly.
• If activation or purchase is blocked because the old-region subscription still exists, the documented options are to wait for it to expire or cancel it. A subscription for the new region cannot be purchased until the existing one is gone.

If the expired subscription shows as past due, open Services & subscriptions and look for Pay now. If the goal is to move the subscription to France, paying the old UK subscription will not change its billing country.
