To see which machines are signed into your Microsoft 365 subscription go here in your Microsoft account online. That means you can just sign-in to any device with Microsoft 365 software and let Microsoft’s servers handle the five device limit. It will be the device with the oldest login. Now, if you try to signin to Microsoft 365 software from a sixth device, one of the currently signed in devices will be remotely signed out. Microsoft changed that in 2019, after realising they could manage the limit with less hassle for the customer. To continue you had to logout of another computer/device.

If you sign-in to Office with your account on a sixth device, there was a ‘limit reached’ message. – one user who can sign-in to Office software on five devices at the same time. – each of the SIX users can sign-in to Office software on five devices at the same time. – one user who can sign-in to Office software on five devices at the same time. Office will only fully activate on the current five logins you make from the software. Office software/apps can be installed on as many computers/devices as you like. It will only work in a very limited way (Viewing and Printing) until someone signs-in again. When you sign-out of Office on a computer, that software is deactivated.

If you are a subscriber, then Microsoft will allow your Office software to run with all the features. Office will check with Microsoft’s servers to see if your Microsoft account is linked to a current Office/Microsoft 365 subscription. Microsoft will keep a count on how many sign-in you have at any time.Įach sign-in will activate the Office software. You’ll be able to use Office on up to FIVE devices/computers at a time.
