Frequently Asked Questions

Can I change my Microsoft 365 tenant country myself?

No, changing a tenant's country or region is not a self-service option in the admin center. You must either contact Microsoft Support to initiate a complex migration process or set up an entirely new tenant in the desired country and manually migrate your data.

How long does it take to get a tax residency certificate from Microsoft?

The processing time can vary based on Microsoft's current support volume. It is best to open a billing support ticket via the Microsoft 365 admin center to get an estimated timeline directly from the Microsoft Billing Team.

Where can I find invoices for my Microsoft Hong Kong tenant?

You can view and download your invoices directly in the Microsoft 365 admin center by navigating to the 'Billing' menu and selecting 'Bills & payments'.

Does moving my tenant to Ireland affect my existing data?

Yes, migrating your tenant involves moving your underlying services and data to a different geographic data center region. This process requires careful planning and coordination with Microsoft Support to ensure data integrity and compliance.
