New sign-in experience for Office 365, what's it about?
Oh well, so it can be a breaking change also, another rollback incoming...
C_the_S make sure your TAM or the O365 support guys hear your feedback loud and clear on this, hopefully one day Microsoft will finally understand that such changes need to be thoroughly TESTED and ANNOUNCED well in advance.
DaniMartMS another ping, there's definitely some useful feedback for you guys to gather from this thread!
The Office365 support (via the Admin Center) came back with it doesn't work because the new Azure sign-in uses "Modern Authentication" and Office 2010 doesn't support it, but Office 2013 & 2016 do. They proceeded to tell me the fix is to update to Office 2013 or 2016.
Someone here has reached out to me via these forums and I'll see where that goes.
