MS being evil:
Ok, so for various reasons, I've been using OneDrive for many years. In addition to the 1TB with my 365 subscription, I've been paying for an additional 600GB.
When they added CoPilot and raised the price to 365 by 30%, I said no thanks and opted for the "classic" version.
Without telling anyone, either me, or their support people, they removed the ability to add storage > 1TB to "classic".
So now this morning, I am suddenly over my limit by 600 GB
