Data sov­er­eign­ty comes first.

You don’t want to be con­strained by an O365 cloud and see the depen­den­cies on large providers that process your data world­wide as crit­i­cal? We offer you an alter­na­tive with grom­mu­nio as a pow­er­ful and effi­cient col­lab­o­ra­tion tool. With email man­age­ment, cal­en­dar func­tions, task and con­tact man­age­ment, you have all the func­tions of a clas­sic email pro­gram. How­ev­er, you also have access to addi­tion­al func­tions such as file shar­ing, chats and video con­fer­enc­ing.

grom­mu­nio is an open source based group­ware prod­uct with sup­port­ed fea­tures and offers com­pa­nies and users var­i­ous pack­ages as sub­scrip­tions.

As the first open source solu­tion with a ful­ly func­tion­al imple­men­ta­tion of Out­look Any­where (RPC-over-HTTP) and MAPI-over-HTTP, grom­mu­nio is the alter­na­tive to pro­pri­etary back­ends for native inter­op­er­abil­i­ty with Microsoft Out­look.

With its effi­cient and opti­mized design, it even out­per­forms its pro­pri­etary coun­ter­parts in most areas.

With the Lin­ux plat­form as the basis, and the asso­ci­at­ed scal­a­bil­i­ty and man­age­abil­i­ty, grom­mu­nio con­vinces with its large vari­ety of imple­men­ta­tion sce­nar­ios in your data cen­ter.

With grom­mu­nio, a long-await­ed ade­quate prod­uct for the con­ven­tion­al Win­dows world with out­stand­ing user-friend­li­ness has final­ly been estab­lished.
