By default, a Microsoft account will accept a login attempt from anywhere in the world.
Most attacks on Microsoft accounts come from overseas, from automated tools trying stolen passwords by the thousand. If your business only works in one or two countries, there's no reason to allow a login from anywhere else.
There's a setting in Microsoft 365 called Conditional Access that lets you block any login from outside the countries you operate in. Someone trying your password from the other side of the world is turned away, even if the password is right.
It won't stop everything, and a determined attacker can route through your country to get past it. But it blocks the flood of automated attempts from places you'll never deal with, and that's most of what you're up against.
You'll need the right Microsoft plan, and it's set up in the admin area, so ask your IT provider to turn it on and set the countries you work in.
