Blank page in IE stuck on login.microsoftonline.com opening SPO, office.com
This only happens on Windows 7 PCs and i've been told by support this is because Windows 7 doesn't support Modern authentication. They also suggested to try adding our sharepoint.com site to Trusted or Intranet zone. But then it gets stuck on login.windows.net. They say same should happen when using ADFS (we only use AD Connect now). I guess we will have to postpone SSO until all our PCs are on Windows 10. Which will be only in a few years probably.

Actually, have asked our partners about this and they told us that it should work with Windows 7 and they had clients using Windows 7 that they have deployed SSO for. It could be a matter of some missing update (we only install security and critical). So, MS support was too quick to dismiss this and to advertise Windows 10. Though i feel it can still be tricky to find out what is missing.
This issue stopped happening on its own sometimes around after the September security and critical updates for Windows/IE, etc.
