I need to add a ArcGIS Online User to my ArcGIS Online Group. My group is setup through an organizational account, however, the user I am trying to invite is a member of a different organizational account. They just recently became a member of their organizations, organizational account. I have tried searching for their name but I am not seeing it.
Any tips and/or directions to get invite and/or give them direct access to my ArcGIS Online Group?
