there is no rule, you can export a Mesh with high skewed elements, and run your job.
But with experience you will see, that convergence can ba affected by bad cells.
For me I would say
*skewness < 0.9 (for tetra)
*skewness < 0.8 (for hexa)

examining the mesh quality
 
once you\ve imported the *.msh to fluent,type in 'GRID quality' ,fluent will display the statistics of the your mesh.but sometimes you can get your ideal result with a relatively bad mesh quality!anyway a good mesh can help you save some time
