A:AnswerThe cost for the second year is what ever the going price is at Microsoft for 365....probably over $100.00. You can cancel Automatic renewal anytime before your first year is up from where you purchased it.
A:AnswerI assume the device you bought came preinstalled with Win10. Should need to do nothing other than turn it on. If it came with windows 7 return it right away.
A:AnswerAssuming you are using outlook under 2013, first thought is to start your office/Microsoft 365 account. Add that account to your outlook in 2013 copy your contacts from existing contact folder to office 365. Log into office365 outlook via browser and make sure your contacts are there. Then you can uninstall 2013 and install microsoft365 if needed.
I am sure there are migration tools available too but for 6 PCs maybe easier just to manually do it.
Copy your data prior too. I would Make a VM out of each pc so you can get to the old configuration if needed.
A:AnswerI have been able to stack subscriptions at least 1 year more. Not sure if their is a max But if you see a deal on a 1 year subscription I you can add the 12 months to the end of your current subscription. You can always chat with MS to be sure as policy does change.
A:AnswerYou can install it on all your devices. The Microsoft 365 Family subscription allows you to share the subscription between 6 people who all get to install it on their devices and access their own 1TB of OneDrive Cloud Storage.
