Microsoft describes the result as virtual separation, which means ABPs customize what people see in the directory and do not create a legal, security, or compliance boundary.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;134233118&quot;:false,&quot;335559738&quot;:240,&quot;335559739&quot;:240}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">That distinction matters the moment a business unit asks for its own directory.
