Microsoft 365: Where your data lives, you decide — until December 14

TVS News AI, editorially supervised, presents Microsoft 365: Where your data lives, you decide — until December 14.

Cloud storage locations are usually a black box — you don't know exactly where your data lives. With Microsoft 365, the choice is open until mid-December. IT administrators can determine the storage location of their data themselves.

According to heise online, IT administrators have until December 14 to set the storage location of their Microsoft 365 data. Two options are available: storage in their own country or within the EU.

This gives companies direct influence over data residency — relevant for anyone who values data sovereignty, GDPR compliance, or clear responsibilities for government requests.

What choice do IT administrators actually have?

According to heise online, two options are available: your own country or the EU. Which countries are available in detail and which Microsoft 365 services specifically fall under the storage location choice is not revealed in the brief heise note. Microsoft has gradually expanded the choice over the past months, with the company publishing details in its documentation.

Why the December 14 deadline matters

Anyone who lets the deadline pass forfeits their own influence over the storage location — Microsoft will then decide according to its own standard. Especially for German and European companies, the EU option is often the pragmatic middle way: the data stays on European soil without having to commit to a single country. The jurisdiction of data protection authorities and the reach of government information requests also depend on the storage location.

What IT administrators should do now

• Mark the deadline in your calendar: December 14 is hard — no choice after that.
• Clarify with the data protection officer and management which option makes strategic sense.
• Inventory: which tenants and which services are in use?
• Check whether a later location change is possible or whether it's set once and for all.
• Document the decision — for example, in the record of processing activities.
