Hi apoorvam0001,
If you want to fetch users from some group and get their email,
used following function to get user list related to specific Group

"getdirectgroupmemberuserspaging(getgroupbyname("Group_Name"),0,-1)"

but remember,
if you are using these function you should aware about security of Basic user, because security is not set
then these function will not work for basic user,
and already i am using these function in one of my project.
if not work please convey me...
