As per a case with MS TrackingID#2308240030000032, below switch doesn't work now and they are deprecated for Office 365. If they are deprecated, they should be removed from the article or should mention it only works for users with no signature and will only work for On prem exchange servers

@chrisda do we have any update on when the article will be updated with correct information
