Slightly OT but since you already have Office 365 on your desktop why not install WPS office on your laptop -- this is FREE and almost a total clone of Ms Office - documents are also interchangeable.
The main difference is that in the FREE version the EXCEL equivalent won't run VB macros - but it can still do very complex spreadsheets 100% compatible with Ms EXCEL and there's no email client - but it beats Libre or Open Office by a Universe (and also runs in Linux if anyone is interested). BTW also works on Android phones too for those who read Office / Work documents on your phones.
Multi Language Free Office for PC, Laptop
The PAID version (49 USD one time fee) will soon have email support so I expect FINALLY a decent OUTLOOK clone to appear as email client plus it seems to handle VB too in EXCEL.
