A federal judge has dismissed Microsoft’s bid to quash a warrant for the search of a user’s email account information which is being held at a company-owned server in Ireland.

Though Microsoft insisted the warrant was an impermissible extraterritorial search and seizure, U.S. District Judge Loretta Preska in Manhattan agreed with federal prosecutors that the key matter in the closely-watched dispute was whether the domestically-based entity­—Microsoft—exerted control over the subject information.
