Office 365 is a great way to access Microsoft's suite of office tools on a subscription basis. It ensures you won't be left in the dust when a new version of the product comes out because your Office is going to be kept up to date as long as you're a subscriber. Did you start with Office 365 Personal but now need Office on multiple computers, tablets, and phones? No problem. Upgrading from Personal to Home edition won't take long.

Comparing Office 365 subscriptions
There are a couple of options to choose from when purchasing a subscription. Both get you access to excellent Office tools like Word, Excel, PowerPoint, and Outlook. Where the subscriptions differ, however, is in how many individual devices can use Office 365 simultaneously, as well as how many users get an Office 365 license.
On top of the number of devices that can be used, including OneDrive storage, also differs between Personal and Home subscriptions. With a Personal plan, you'll get 1TB of OneDrive storage for one user. If there are more people vying for space, a Home subscription gets 1TB of OneDrive storage for six people. That's 6TB total storage spread out over the six licensed users.
Note that in the past you were only able to install Office 365 on a certain number of devices; this has now changed to an unlimited number of devices, though you can only be signed in on up to five devices at once.
If you initially purchased Office 365 Personal but now need Office for multiple people, fret not. Upgrading to Office 365 Home from Personal is a snap.
