I'm using SharePoint Designer 2013 and I have a list that I created from an excel spreadsheet that have several columns and rows. One Column is labeled as
"Assigned To", it may have some data populated in a couple of rows but a majority are just left blank currently.
My problem is I cannot figure out how to force that column to search Active Directory for results. I would like to either make it so the user clicks a button and they can search active directory or as they type names a persons name will show up as auto populated data. Then once they save that item that user that was just assigned the item will get an email saying it was assigned to them.
