Phew, I fixed it.
I fired up WaterFox and went to outlook webmail. I looked over the options and apparently I have to allow Office 365 even though I don't use it. (I had tried IE but apparently my activex allowances weren't correct because it kept saying javascript was turned off. I don't use IE enough to be good at its settings.)
I got in with Waterfox then saw an email. I then fired up Palemoon and although it looked like everything was allow, it showed what was recently blocked. Office 365 was in the list. I allowed it and the error went away.
