Hello All,

In my org there are around 150+ profiles and now my requirement is to disable "Mass Email Functionality " for an entire org.

Im checking the below two options 

1) Disable "Mass Email" checkbox from General User Permissions Settting from Profile Level .Can you pls let me know is there any workaround instead of going to each profile and edit the settting .Can this be acheived for all profiles at a time??

2) From Set Up-->Email Adminstration-->Deliverabilty-> System Email Only .But this option seems to invalid .

Could you please check and provide any workaround for this ??
