Our groups are automatically synced in but when I add security to a site I use the AD group from AD and then in the Show Users box it only shows the group not all the users in the group. So if we want to send emails to individuals in that group and not the whole group I have to set security on the site/list using each user (so their name shows up in the Show Users Box). Therefore it makes it hard to set security using our synced in AD groups because we need the users to be able to select individuals for those emails. Does that make sense? If we use the people picker it works fine with the security being set like it is…that's why I wondered if we could change the email one to the people picker.
Thanks for your help.
