MY Frustration with this issue is off the chart.  It is 8pm on a Sunday.  All of a sudden my users can no longer use word.  We get an error message "

your organization needs more information to keep your account secure office 365"

I have never turned on Multifactor authentication for my company.  Some how it is now turned on.  I am now in some azzure directory trying to turn off multifactor authentication.  Why is there no phone support for paying customers?  I can't buy or purchase any phone support.  How in the world am I supposed to get support for something that should not be a problem in the first place.  Why would Microsoft change policies on my account on a Sunday? Why are they forcing multifactor authentication?  Why can I not just buy a stand alone version of office any more?  Why have I wasted over two hours of my weekend to get something working that was working just fine on Friday?  I would love a phone call on this 425-766-0536.
