Will Office 365 run successfully under Windows 7 after 1/2020?

For the umpteenth time, I installed Windows 10 on my PC and came to the same conclusion -- I don't like it.  I have decided to revert back to Windows 7 Professional.  I use MS Office 365 and wondering if I will still be able to use it after January 2020 when support ends for Windows 7?

Thank you.

Hi Andrea,

It would continue to work, however only until 2023.


Using Office 365 on older, unsupported operating systems may cause performance and reliability issues over time. As a valuable Office 365 subscriber, we want to continue to provide a stable Office 365 experience. Therefore, if you're using Office 365 on a computer running Windows 7 we strongly recommend you move to Windows 10.

Even though Windows 7 will no longer be supported after January 2020, we’ve decided to continue to provide you with security updates for Office 365 for the next 3 years, until January 2023. We’re doing this to give you additional time to make the transition from running Office 365 on devices running Windows 7 to a supported operating system, such as Windows 10. But, during that time, as long as the device is still running Windows 7, Office 365 won’t receive any new features updates.
