Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Lin,
I'm Sumit, here to answer your query at the Microsoft Community.
Apologies for any inconvenience you are experiencing. I am happy to help you today.
There will be no issues using the Microsoft 365 Family plan purchased in Taiwan while you are in the UK for university, and your family remains in Taiwan. Microsoft 365 Family subscriptions do not have geographical restrictions on usage once activated. The geographic limits only apply to the purchase and activation of the subscription, meaning you can use and share it across different countries without any problems.
However, the subscription renewal must be done in the country where it was originally purchased, which in your case is Taiwan. This means you will continue paying in NTD even while residing in the UK. Additionally, each user can set up their software in their preferred language and access Microsoft 365 apps on multiple devices
Hope that helps, and rely on us for any further inquiries. All the best.
