Patty has forgotten her username and password for a new Office 365 login and can't remember it. Leo says that Patty's other accounts will still work. What about her Outlook account? Leo says that she could call Microsoft and let them know what her account number is and they'll help her create a new account. They may also be able to tell her what her account is by using her secondary recovery login/password credential.
Valerie wants to know if she doesn't use Office 365/2013 next year, will she be able to open the documents? Leo says there are free, open source options like OpenOffice, which will open the docs Valerie uses with no trouble. In fact, Microsoft's own TOS says:
Tom just bought Microsoft Office 2010 and now they've released 2013. Should he upgrade again? Leo says no, that's not necessary. He doesn't need to spend $100 a year to subscribe unless he needs the Microsoft cloud options. He would get five installs though, plus Office 365 online. But he can do everything in 2013 in 2010 with only a step or two extra. So he should just stick with 2010.
Think of it this way: Office 365 is "renting" office by using online versions of Word, Excel, Powerpoint, Email, and more. Office 2013 is the desktop version which would also include the online version of Office. It costs more to get Office 2013, but then he would actually be able to use both versions.
