Consider for example, a system in thermal equilibrium with a heat bath, with a fixed number of particles and a fixed volume. The macrostate is defined by the variables T, V and N.
The energy of the microstates corresponding to the macrostate is not fixed. The probability of each microstate is proportional to the exp(-E/kT). https://en.wikipedia.org/wiki/Boltzmann_distribution https://en.wikipedia.org/wiki/Boltzmann_distribution
The microstates don't have a temperature: they are more or less likely to happen depending on the temperature.
And that's assuming a particular thermodynamical model. The same microstate could be looked at in the context of a different thermodynamical model as a different (or differents) macrostate(s) characterized by another set of thermodynamical variables.
