I have a People Picker column in one of my lists and it can pull users and security groups but not Distribution Lists. Is there any way to make it pull from Distribution Lists or do you know of any tools that would do this?
I know that you can make distribution lists into security groups but we already have a large amount of pre-existing distribution lists that we would have to change. In addition I read from this forum that having a user in a lot of security groups increases the footprint of their usertoken.
