They will deliver less power abour 50/60 of what you expect.
The power supplies in those ovens are quite inexpensive and use a single
rectifying diode. When the voltage gets high enough, the microwave bursts
on for a short time. Thus, if operated from 50 Hz instead of 60 Hz, the
power will drop proportional to the frequency.
Don't know about any deleterious effects that would cause concern.
