The W3WP.EXE process for the exchange application pool is consuming 100 of CPU time. I've tried everything I know, configuring recycling, changing authentication, I even deleted all the virtual directory and re created them; but the problem still exist. I have form based authentication enabled. I created a new VD for OMA and disabled ssl on it (as suggested y microsoft). Can anyone please help me
