After doing a deep analysis, we conclude that Exchange Server gains more popularity rather than Lotus Notes. Thus, if you are a Lotus Notes user and wish to export Lotus Notes to Exchange then, you are required to take help from a third-party tool as there is no any manual method to do so. Thus, we recommend to use SysTools Mail Migration Wizard to transfer Lotus Notes data to Exchange Server.
