well.. after logging in with the attached email and code for it.. i finally got the office 365 pro plus app, and installed it OK. I could change the password > OK I can not add or change the mail-address !! AND !! they forgot to tell that it is NOT a "private" account you buy. It is just an account in a company called "Asian Answers" and there is NO WAY you can get your account separated. If you then choose to live with being an "employee" in " Asian Answers" you also have to accept that you cannot add alias, other mail-address for recovering the account. you also can not see which devices there is activity on, on "your" account. There is no family sharing, so the 5 licence app is quite useless, because your family only can login to your one account in " Asian Answers"'s microsoft account, to download and install the remaining 4 "apps" / licences... with NO option to personalize it. .. please to consider this before buying.
