直接修改SharePoint 数据库更改用户信息，要修改两个表

update UserInfo set tp_Email='' where tp_Login='domain\test' select * from AllUserData where tp_ListId=(select tp_ID from AllLists where tp_Title='User Information List')

update AllUserData set nvarchar4='‘ where tp_ListId=(select tp_ID from AllLists where tp_Title='User Information List') and nvarchar3='domain\test'
