What would happen if someone with O- blood received blood from any other blood type donor?

Well, there are some blood types that are called "universal" (see link, below) so, depending on what they got, it might or might not harm them.

Good luck!... ?

Patients should ideally receive their own blood or type-specific blood products to minimize the chance of a transfusion reaction. Risks can be further reduced by cross-matching blood, but this may be skipped when blood is required for an emergency. Cross-matching involves mixing a sample of the recipient's serum with a sample of the donor's red blood cells and checking if the mixture agglutinates, or forms clumps. If agglutination is not obvious by direct vision, blood bank technicians usually check for agglutination with a microscope. If agglutination occurs, that particular donor's blood cannot be transfused to that particular recipient. In a blood bank it is vital that all blood specimens are correctly identified, so labeling has been standardized using a barcode system known as ISBT 128.

People with "Rhesus-negative" blood cannot handle "Rhesus-positive" blood. They get blood poisoning and could easily die from it - the positive blood kills off the negative blood.
AB+ can accept blood from any donor - they are universal recipients.
O- can donate blood to any recipient - they are universal donors.

The reason blood type is important is that the immune system will attack foreign proteins. If you're type A blood, for example, the body will not attack other type A blood cells, so you will be able to receive them without a problem. But with type O- people, their blood cells don't have A, B, or rh proteins--so if they receive blood that does have one of those proteins, the body sees the cells as a dangerous invader and attacks.

When the immune system attacks blood from a transfusion, it's not pretty. The donor blood will first clot in the veins, as it's surrounded by antibodies and clumped together. Then the immune cells will break down the foreign blood cells, resulting in something called hemolysis--the foreign blood cells literally fall apart under the force of the body's attack. The immune response and the clotting can be deadly. This is why when blood transfusions were first tried in the nineteenth century, they were found to be sometimes lifesaving--but sometimes deadly.

The good news is, there are simple and reliable tests to screen for blood type before getting a blood transfusion! People can generally receive any blood type that doesn't have foreign proteins; type AB+ can receive any blood type, since their body produces all of the blood type proteins, while type O- people can only receive blood from other type O- donors.
