    Folks, for me it was the EWS (exchange web services) being set to ON for the user but OFF for the org.  The whole KB article pointed out they REVERSED THE BEHAVIOR of the setting.

     

    i.e.last week disabled for ORG and ON for user would work.

     

    This week it won't work.  You have to use EWS Enabled TRUE for org AND user

     

    It's not instant gratification when you make the change it may take more than a few hours.

We ran into this same issue around the same time. After MANY hours of scratching our heads, we fixed it by re-enabling EWS. Problem is why it got set to disabled in the first place? Did Microsoft do something?, probably.

Just set the EwsEnabled to True and everything is working again but it is taking a while to propagate out to our users.

Set-OrganizationConfig -EwsEnabled $True
