The best thing about this software for me personally was that I could easily share files with other users without having them download it first, which saved time! Also there were no problems when sharing documents or sending emails from work related stuff as well as personal ones between coworkers who are not using any form of email provider like Gmail etc., just truetrue@gmail.com address would do fine.
So far nothing much has been negative so its pretty good overall but maybe add moreβ¦
