Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hey there!
I'm here to help.
Microsoft ties your subscription to your Microsoft Account region, billing address, and payment method. Once a region is set, it cannot be changed directly within the same subscription.
You’ll need to wait for Subscription to Expire then cancel your current plan. Once it is canceled then purchase a new subscription in the desired country.
If you still need assistance, Please contact Microsoft Support here:
