うれしいはずです　she must be happy!
Something really good happened to the friend of my friend and i want to say "She really must be happy!"
うれしいはずです - ist this correct?
Or does this imply, that she isn't happy but is supposed to be so?

Question

Answer

adjective+はずです  indicate a simple reasoning without the other implication.  
verb+べきです indicates that it has not been realized, but it should.

Answer

"はず"means it should be that but the result is opposite.
So, "彼女（かのじょ）はきっと嬉（うれ）しいですね。" will be better.
