How do the new light probes in EEVEE work?
There are three types of Light Probes
Reflection Cube Map
Reflection Plane
Irradiance Volume
Reflection Probes
The two first are, as the name suggests, to calculate reflection maps for reflective ...

How do I get proper reflections (Eevee)?
By default, Eevee will reflect the HDRI and the lights but it won't reflect the objects of your scene.
For flat surfaces like mirrors you need to create a Light Probe > Reflection Plane. It's easy ...

Rendering a fake mirror
You can use "Is reflection ray" output from "Light path" node and plug it into the alpha input of the "Principled shader".
This will work for both Eevee and Cycles. For ...

Why do reflections on a smooth-cube look more 'definite' than a flat shaded one?
It's an optical illusion. Actually, the flat-shaded cube has a reflection which is more clear and more detailed.
But why doesn't the flat-shaded cube look detailed? It's because the flat-shaded cube ...

Why do reflections on a smooth-cube look more 'definite' than a flat shaded one?
The built-in HDRI images are fairly low resolution, in addition, there is some blur added by default. Finally, your image shows the flat-shaded square pointing at the curtains, which are blurry from ...

Can't get simple uneven reflection map working
Here's my example to show you what you can do. I guess you're right, it's coated for preservation. I've tried my own take on it.
I gave the Principled BSDF a slight (estimated) Roughness of 0.2 for ...

Rendering a fake mirror
You must use the Input > Light Path node as a factor between the material of the object and an Transparent node.
For your green cube use the Is Glossy Ray output (non visible in the mirror):

Why do reflections on a smooth-cube look more 'definite' than a flat shaded one?
When using an HDRI the light is coming into the scene from infinitely far away.
This means when looking at the flat shaded cube it will reflect only a tiny portion of the background. The smooth ...

How to turn off reflections on glass
Glass is supposed to be transparent and reflective (and other thing is refractive, can disperse and absorb light, etc). If you take away the reflections then it will no longer look like glass.

Why do reflections on a smooth-cube look more 'definite' than a flat shaded one?
The other answers are correct: the difference is that the smooth cube reflects a large contiguous area of the room, while the flat cube reflects three small isolated areas of the room. Since a small ...

Blender reflects an HDRI that no longer exists in a project and ignores current ones
You have baked the indirect lightings, so the reflections will stay even if you remove the HDRI. To fix it, delete the lighting cache in the Render panel:

How do I make an object reflect light through a volume at a specific angle?
You can not solve this in an honest way. The implementation of Cycles engine does not allow this.
The bright light in the volume is visible only because the beam knows in which direction the sun is. ...

Same material on different objects, different reflection
In addition to Harry McKenzie's answer
In your material, the normal is image-based, in Tangent space. That means the local 3D spin of X and Y directions about the Z normal is dependent on the U and ...

Reflective Glass shader, like those in our window
The standard Glass shader gives you exactly that.
Or if you prefer Principled BSDF like me:
Set Transmission to 1
Use Roughness and Transmission roughness to control the glass type
Add thickness to ...

Using Cycles renderer the reflections look good in viewport but not in in the render, why is this happening?
The issue is not the reflections, but the fact that they are blocked by something else. It looks like you have another object on top that is not visible in the 3d viewport but is renderable.
Those ...

Why wont the sunlight affect the mirror?
The sun light affects the mirror just the same as the wall.
The reason you don't see any effect is probably because you have a "perfect mirror" made from a 100% perfectly glossy material.
