How to resolve the conflict between two layer labels?

Question

Despite the fact that all labels placement methods and styles was tried ArcMap still fails to resolve the conflict between two layers labels?

In my case, I have two layers (the built-up area) and (well-known sites). And I am using maplex engine I tried all placement and position changing procedures, but unfortunately the labels still have clashes between them as shown in the screenshots below:

Answer 1

You have Never Remove (place overlapping) enabled. This option makes sure the label is always shown on the map, even if it overlaps other labels. Also, you are using a fixed position at the centre of the polygon. This gives Maplex fewer alternative label positions. Try turning both of these options off and your labels should be placed without overlap.
