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.
FYI, this appears to have been a known change with a notification being sent out Feb 25, 2025 but I guess we ignored it in the noise. Not sure if it is the same issue as everyone else but posting just in case.

I fixed it but thanks for absolutely nothing MS. (oh and their L1 tech support made Comcast support in the states look GOOD.
