I have Windows 7 and Office 2016 MSI installer on one of my computers. Computer OS can't be updated for various business reasons.
I'm trying to get Outlook to connect to Office 365 email (broke when they disabled basic authentication).

On another computer I have Windows 7 and Office 2016 Click to run. Outlook and Modern authentication is working on this machine.

I took the same MSI installer from the first machine and installed it on a Windows 10 machine, and I do get the modern authentication login, and this computer connects to Office 365 email as expected. So I know it is possible even for the MSI version to work.

Installed the same MSI installer on a clean Windows 7 VM and have the same issue as the real machine I'm trying to get to work.

Is there a way to get the MSI version to work on Windows 7?
I only have one license for the C2R and need to keep it working on the other machine.

Thank you
