Enterprise Mail supports intra-company communications as a highly functional webmail solution with an enterprise-oriented user interface and advanced search functions. It can be bundled with optional functions for schedule sharing, facility booking and processing/sharing files with tracked changes and comments. Enterprise Mail can be adapted for a small number of IDs, as in the case of companies starting up global bases on a modest scale.

Enterprise Mail's standard global address book displays multiple layers organized by user countries and domains, which helps to simplify communication in corporations operating in multiple countries.

All addresses can be viewed on a global list. Users will eventually be able to manage Enterprise Mail from NTT Com's Business Portal, which provides customers with comprehensive control of everything from network to services.
