We would like to find out the minium permissions required in order for an internal user (Windows authenticated) to invite outside users through InviteUsers.aspx.
We have setup a SharePoint User Group for these internal "invitors". What permissions are required?
Are there other better ways to lock down so that the invitors has minimal rights to do what is necessary?
P.S. So far, I have found that "Manage Permission" and it's depending permissions are necessary.
